IP2368 Function description Charging process IP2368 has a constant current and constant voltage lithium battery charging management system that supports a synchronous switch structure. IP2368 uses switch charging technology with a switching frequency of 250kHz. IP2368 can set different battery types, full voltage and charging current through external resistors, and can support 2/3/4/5/ 6 series lithium iron phosphate or lithium battery charging, the maximum charging current can reach 5A or 100W charging input, charging efficiency Up to 96%; IP2368 supports trickle-constant current-constant voltage charging process: When the battery volta ge VBAT≤2.5V, it is a small current trickle charge, and the battery charging current is about 100mA; When the battery voltage is 2.5V <VBAT≤ VTRKL, it is trickle charge, and the battery charging current is about 200mA; when BAT_MODE is floating, the trickl e charge cut-off voltage VTRKL is N*3V; when BAT_MODE is grounded, the trickle charge cut-off voltage VTRKL is N* 2.5V; When the battery voltage VTRKL<VBAT<VTRGT, it is constant current charging, and the charging current charges the battery according to the set constant current charging current; the full voltage VTRGT and constant current charging current can be set by connecting RVSET and RISET; When the battery voltage VBAT = VTRGT, when the battery voltage rises to close to the full voltage, the charging current will slowly drop and enter constant voltage charging; After entering the constant voltage charging, when the battery charging current is less than ISTOP (100mA) and the battery voltage is close to the constant voltage voltage, the charging is stopped, and the battery is fully charged and then fully charged. After the battery is fully charged and stopped, the battery voltage will continue to be detected. When the battery voltage is lower than VBAT <VTRGT – N*0.1V, the charging will restart; IP2368 can customize different trickle charge cut -off voltage VTRKL, and can also customize 0V battery charging prohibition function; IP2368_COUT needs to be charged and activated before it can be discharged,when the battery is connected for the first time; it can be customized to remove the charging activation function; Type_C PD IP2368 integrates USB Type_C input and output identification interfaces, automatically switches the built-in pull-up and pull-down resistors, and automatically recognizes the charge and discharge properties of the inserted device. With Try.SRC function, when connected to the other party as a DRP device, the other party can be charged first. IP2368 supports PD2.0/PD3.0 bidirectional input/output protocol. Maximum support 100W power Version1.35 TEL: +86-0755-27595155 27595165 FAX: +86-0755-27594792 WEB:Http://www.ChipSourceTek.com E-mail: Sales@ChipSourceTek.com Tony.Wang@ChipSourceTek.com 矽源特科技 ChipSourceTek
output, input support 5V, 9V, 12V, 15V, 20V voltage range, output support 5V, 9V, 12V, 15V, 20V voltage range. IP2368 customization can realize PPS output function; Fast charge function IP2368 supports a variety of fast charging modes: QC2.0/QC3.0/QC3+, FCP, AFC, SCP, Apple. Charging the battery input can support fast charging inputs such as FCP and AFC. Since FCP and AFC are used for fast charging handshake requests through DP/DM, when other fast charging protocol ICs are added, FCP and AFC fast charging can no longer be supported. IP2368 integrates AFC/FCP/PD2.0/PD3.0 input fast charging protocol, you can apply for fast charging voltage to the fast charging adapter through DPC/DMC/CC1/CC2 on the TypeC port, and it will automatically adjust the charging current to adapt Adapters with different load capacities. When charging with an ordinary 5V charger or power supply without fast charging, the maximum maximum charging current at the input terminal will be set to 3A; When charging with a charger that only has Huawei FCP or Samsung AFC fast charge protocol, but does not have PD fast charge, the maximum charging power at the input end will be limited to 18W (9V/2A, 12V/1.5A); When charging with a PD fast charge adapter, the maximum input charging power will be limi ted according to the received PD package. When the received PD package power is less than the power required for charging set by ISET, the charging current will be actively reduced to maximize the input end The power is less than or equal to the PD broadcast power given by the adapter; For example 1: ISET_MODE is floating, RISET=15K, and the maximum input power during constant current charging is set to 60W. If a 30W PD adapter is used to charge the IP2368, the input charging current will be limited to 30W; only a PD adapter of 60W or more is used Charge the IP2368, the input power will reach the set 60W; For example 2: ISET_MODE is grounded, RBAT_NUM=9.1K, 3 strings of batteries are charged, RISET=15K, the maximum charging current of the battery termin al is set to 3A, the 30W PD adapter is used to charge the IP2368, and the PD fast charge is successfully entered, regardless of charging conversion Efficiency. When the battery voltage VBAT<10V, the charging power is less than 30W, and the maximum output p ower of the adapter is not reached. The battery charging current can guarantee 3A constant current charging; when the battery voltage VBAT>10V, the power required for charging is already greater than 30W, exceeding the maximum output power of the PD adapte r, so it will automatically reduce the battery charging current to maintain the input power at 30W; If the charging input is a fixed voltage input, not the adapter used, you can use a customized model of IP2368_NA; Regardless of the adapter power, the customized model of IP2368_NA will be charged according to the input power or battery charging current set by the ISET pin, and will not automatically reduce the charging power or charging current, but it is necessary to ensure that the power load capacity of the charging input is greater than the set maximum charging power ； Version1.35 TEL: +86-0755-27595155 27595165 FAX: +86-0755-27594792 WEB:Http://www.ChipSourceTek.com E-mail: Sales@ChipSourceTek.com Tony.Wang@ChipSourceTek.com 矽源特科技 ChipSourceTek
When the battery is discharged externally, it automatically detects the fast charge timing on the DP and DM pins, and intelligently recognizes the type of mobile phone. It can support mobile phones with Android phone 1A mode. Setting the number of batteries in series IP2368 can support the charging of 2/3/4/5/6 strings of batteries; IP2368 can select and set the number of batteries connected in series by connecting different resistors to the BAT_NUM pin; The relationship between the external resistor RBAT_NUM of the BAT_NUM pin and the number of battery cells in series is as follows: BAT_NUM RBAT_NUM IP2368 When the RBAT_NUM resistance is greater than 33K, it will be detected that the RBAT_NUM resistance is open. In order to ensure the safety of charging, the charging status indicator will give an abnormal alarm; Battery type and full voltage setting The BAT_MODE pin of IP2368 is left floating, select ordinary lithium battery, the full voltage range of a single battery is 4.1V~4.4V; BAT_MODE pin is grounded, select lithium iron phosphate battery, the full voltage range of single battery is 3.5V~3.7V; The relationship between VSET pin ground resistance RVSET and the set full voltage is as follows: Version1.35 TEL: +86-0755-27595155 27595165 FAX: +86-0755-27594792 WEB:Http://www.ChipSourceTek.com E-mail: Sales@ChipSourceTek.com Tony.Wang@ChipSourceTek.com 矽源特科技 ChipSourceTek

For the full voltage of a single battery set by RVSET, the actual BAT output voltage must be multiplied by the number of battery cells; 2. The voltage setting step for full voltage of a single battery is 10mV. In order to ensure accuracy, RVSET should use a 1% precision resistor; 3. When the RVSET resistance is greater than 33K, it will be detected that the RVSET resistance is open. In order to ensure the safety of charging, the charging status indicator will alarm abnormally; Charging current setting IP2368 can set the charging current through the ISET pin; When the ISET_MODE pin is floating, the ISET pin sets the maximum input power during charging. During constant current charging, the input voltage and current remain unchanged. As the battery voltage rises, the charging current at the battery terminal will decrease; When the ISET_MODE pin is grounded, the ISET pin sets the charging current of the battery terminal. When the input load capacity is sufficient, the charging current of the battery terminal remains constant. As the battery voltage rises, the current and power at the input terminal will increase; The relationship between ISET pin resistance RISET and the set input power or charging current is Version1.35 TEL: +86-0755-27595155 27595165 FAX: +86-0755-27594792 WEB:Http://www.ChipSourceTek.com E-mail: Sales@ChipSourceTek.com Tony.Wang@ChipSourceTek.com 矽源特科技 ChipSourceTek

When setting the input power, the minimum step is 1W and the maximum input power is 100W; when setting the battery current, the minimum step is 100mA and the maximum input current is 5A; when the RISET is greater than 25K, it will be set to a maximum of 100W or 5A for charging; 2. When the RISET resistance is greater than 33K, it will be detected that the RISET resistance is open. In order to ensure the safety of charging, the charging status indicator will alarm abnormally; 3. The standard product will automatically adjust the charging current according to the power supply capacity of the charger used; if the power supply capacity of the charger used is less than the charging power set by RISET, the charging current will be automatically reduced; 4. If the input power is not a third-party charger, but a fixed input power, you can use the customized model of P2368_NA, which will not automatically reduce the charging current according to the power supply capacity of the charger; IP2368_COUT supports the C port discharge output function. The discharge output PDO can also be set through the ISET pin.

IP2368 integrates NTC function to detect battery temperature. After the IP2368 is powered on, the NTC PIN outputs 80uA current at high temperature and 20uA current at low temperature. The voltage is generated by the external NTC resistor. The IC detects the voltage of the NTC PIN pin to determine the current battery temperature. ADC RNTC=10K B=3380 NTC_ADC20uA / 80uA Figure 12 Comparison of battery NTC In the charging state: the NTC temperature is lower than 0 degrees (0.55V) to stop charging, the normal charging is between 0 and 45 degrees, and the temperature exceeds 45 degrees (0.39V) to stop charging. In the discharge state: when the temperature is lower than -20 degrees (1.39V), the discharge is stopped, the discharge is normal between -20 degrees and 60 degrees, and the discharge is stopped when the temperature is higher than 60 degrees (0.24V); *The NTC resistance parameter referenced in the above temperature range is 10K@25℃ B=3380. Other models have differences and need to be adjusted. If the solution does not require NTC, a 10k resistor must be connected to the NTC pin to ground, and it cannot be left floating or grounded directly.
