Description
The DIODES ™ PI5USB30216C provides a cost -effective solution for USB 3.0 Type -C connector applications. PI5USB30216C detects the plug-in orientation of the cable at a Type-C connector. It supports host mode, device mode and dual role mode ports with automatic configuration based on the voltage levels detected on CC pin s. It is a fully -integrated solution with ultra -low power dissipation. PI5USB30216C enters power-saving mode when ENB pin is pulled up to VDD through an internal resistor. PI5USB30216C supports both pin and I 2C control base on ADDR pin setting. It allows the system choose between pin control and I2C control mode. In pin control mode, the PORT input pin determines the port setting in which host, device or dual-role port can be selected . In host mode, the system can monitor ID pin to know the connector status while d efault current mode is set. Systems running in device mode can monitor system VBUS for connector status as well as OUT1 and OUT2 pins for host’s charging profile capability. Enabling I2C control mode allows higher flexibility for port control and communications through registers read/write in PI5USB30216C. There is also flexibility to su pport Default, 1.5A and 3A current modes. An interrupt signal for indicating changes with the I 2C registers is sent to the master to notify the system any change in the Type -C connector while in parallel the system can still monitor ID pin. Notes: 1. No purposely added lead. Fully EU Directive 2002/95/EC (RoHS), 2011/65/EU (RoHS 2) & 2015/863/EU (RoHS 3) compliant. 2.

PI5USB30216C www.diodes.com June 2022 Document Number DS44976 Rev 1-2 8 ©Diodes Incorporated PI5USB30216C Detailed Description using I2C Control ADDR ADDR is a tri -level input pin to indicate I2C or pin control (or GPIO) mode. When ADDR pin is floating, the part is set to pin control mode. When ADDR is set to VDD or GND, I2C mode is enabled, and bit 6 of I2C address is equal to 1 or 0 according to ADDR set to VDD or GND (see Table 2: I2C Slave Address). Configuration The PI5USB30216C requires minimal configuration for proper detection and reporting. Write r egister 0x02 (Control Register) to configure different charging profiles and port settings. Processor Communication Typical communication steps between the processor and the PI5USB30216C during plug detection are: 1. INTB asserted LOW, indicating changes in register 0x03 (Interrupt Register) or register 0x04 (CC Status Register). 2. Processor reads Interrupt registers to determine which event occurred. Interrupt R egister (0x03) indicates if an attach or detach event was detected. All interrupt flags in Interrupt Register (0x03) will be cleared after the I2C read action. INTB will become hi-z again after the clearance of interrupt flags. 3. Processor reads CC Status Register (0x04) to determine plugin details and charging profile. Processor can configure the power and USB channels according to information in CC Status Register (0x04). Interrupts The baseband processor recognizes interrupt signals by observing the INTB signal, which is active LOW. Interrupts are masked upon bit 0 of Control R egister 0x02 (Interrupt Mask Bit ). After the Interrupt Mask Bit is cleared by the baseband processor, the INTB pin is hi-z in preparation for a future interrupt. When an interruptible event occurs, INTB pin transits to LOW and returns hi-z when the processor reads the Interrupt R egister (0x03). Subsequent to the initial power up or reset; if the processor writes a “1” to Interrupt Mask Bit (bit 0 of Control Register 0x02) when the system is already powered up, INTB pin stays hi -z and ignores all interrupts until the interrupt mask bit is cleared. Besides monitoring the I2C registers, the system can also monitor ID pin and VBUS for connector status. If the port is configured as a device (or dual-role acting as device), VBUS will go to 5V when h ost attachment is detected. If the port is configured as a host (or dual-role acting as host), ID pin will pull low when device attachment is detected, and system should assert VBUS. Port Setting (Host/Device/Dual-Role) When power is applied to VDD, an in ternal Power-On Reset (POR) holds the PI5USB 30216C in a reset condition until VDD has reached 2.6 V. At that point, the reset condition is released and the PI5USB30216C registers and I2C -bus state machine will initialize to their default states. After power up, the port setting can be changed by I2C writes to [2:1] of Control R egister (0x02). Thereafter, VDD must be lowered below 1.0V to reset the device (both registers and I2C-bus state machine). PI5USB30216C connects current sources to CC1 and CC2 when ope rating in host mode. It will also set the current level according to the charging current setting. In device mode, PI5USB30216C will connect two integrated resistor Rd1 and Rd2 to CC1 and CC2 respectively. Dual-Role & Dual-Role 2 modes enables CC1 and CC2 toggle between host mode and device mode alternatively . The toggling will stop after connection is made and role negotiated . Dual-Role mode has similar chances to connect as SRC or SNK . Dual-Role 2 with Try.SNK supported has higher chance to connect as SN K and has a longer duty cycle ~65% in device mode. Dual -Role 2 with Try.SRC supported has higher chance to connect as SRC and has a longer duty cycle ~65% in host mode. Current Mode Setting and Detection PI5USB30216C can be configured as different current modes per CC1/CC2 setting. Host mode (or dual role acting as Host) allows the system to configure between High Current M ode (3A), Medium C urrent Mode (1.5A) and Default Current M ode. Different current modes can be set by writing C ontrol Register (0x02). When in Device mode (or dual role acting as device) , CC1/CC2 pins allow the system to detect the host charging capability. The charging capability is reported in CC S tatus Register (0x04) which can help the system to configure the charging current accordingly.
PI5USB30216C www.diodes.com June 2022 Document Number DS44976 Rev 1-2 9 ©Diodes Incorporated PI5USB30216C ID When PI5USB30216C is configured as host mode (or dual role acting as host) , ID pin will be pulled low when a device is attached to the type -C connector. The ID pin will work as an interrupt signal to acknowledge system when there is device at tachment. It should be noted the ID pin will not be driven low when an audio or debug accessory is detected, and ID pin will always stay Hi-Z when port is in device mode. Audio Adapter Accessory and Debug Accessory Mode PI5USB30216C can detect audio adapter accessory or debug accessory attachment as per CC1/CC2 setting. This is reported in CC Status Register (0x04) to help system to configure Audio Adapter Accessory Mode or Debug Accessory Mode accordingly. VBUS Detection PI5USB30216C detects VBUS to d etermine the attached state when port is a device. A 9 10kohm +/- 5% is required to connect VBUS of the connector to VBUSDET input pin to protect the IC from the possible high voltage of VBUS during alternative mode. ENB ENB is an active low enable input pin. When ENB pin is high, part is in disable and low power state. All outputs, with the exception of CC1, CC2, SCL, SDA & INTB are in High-Z state. CC1 and CC2 pins are pulled low with resistors Rd in disable state. I2C port will also be reset during d isable state. SCL & SDA are still functional when the part is disable and ADDR is not floating. I2C port will also reset during every transition (rising or falling edge) of ENB. Connection State will also be reset and for ced to be “DISABLED” state. Interrupt will be set low and Register 03H/04H (Interrupt/CC status) will be updated to indicate the change of state. However, disable has no effect on the value of Register 02H (Control). When ENB pin is low, part is enabled. The connection state will activate and detection will restart. Dead Battery Startup PI5USB30216C ensures dead battery charging when VDD=0V. Both CC1 and CC2 will be pulled down when VDD=0V. Such configuration helps other host port detect the dead battery port as a device mode port and ena ble charging through VBUS.
