In charger applications, the large load will cause voltage drop in the output cable. The uP9601T has a built-in cable compensation function. When the load increases, the cable compensator will increase the adjustable regulation of the error amplifier that keeps the output voltage constant. Use the graphs and table to adjust the internal reference voltage values for fixed USB and adjustable cable compensation by external resistance RSENSE = 50m Ω (default), as shown in Figure 1 and Table 1. The RCOMP is an internal equivalent resistor. The fixed and adjustable cable compensation is calculated as follows: COM PLOADCOMP RIV x = 100 150 200 250 300 350 400 0 500 1000 1500 2000 2500 3000 RCOMP = 15mV/A (adj.) R COMP = 30mV/A (adj.) R COMP = 60mV/A (fixed) RCOMP = 90mV/A (adj.) RCOMP = 120mV/A (adj.) R COMP = 150mV/A (adj.) Functional Description CV/CC Mode Control The uP9601T provides CV/CC function. It operates in either CV (Constant Output Voltage) mode or CC (Constant Output Current) mode and provides a current limitation function and adjusts external current limit setting (default = 2.6A). In the CV mode, the output voltage is controlled within +1.5%. In the CC mode, the output current variation is less than +3% of the nominal value which can be set up to 3A by the current sensing resistor. When Output current increases until it reaches the CC limit set by the RSENSE resistor, the device will switch from regulating output voltage to regulating output current, and the output voltage will drop with increasing load. The CC (Constant Output Current) limit is set at 2.6A by default with an external resistance RSENSE = 50mΩ , When the (SENSE1+) - (SENSE1-) voltage gets higher than 130mV and reaches the current limit, the driver is turned off. The CC (Constant Output Current) limit is set according to the following equation: CC (Constant Output Current) Limit SENSER 130mV = USB Cable Resistance Compensation Select Leave COMP_SEL pin floating (Signal H) or connect an R COMP_SEL resistor < 200kΩ between COMP_SEL and GND pins (Signal L) to select USB cable compensation to prevent output voltage drop in the output cable, as shown in Figure 1 and Table 1. Enable Control and Output Cable Resistance Compensation The uP9601T p ulling EN/COMP pin < 14kΩ to GND disables the car charger, and the EN/COMP pin internally pulls high to enable the car charger. Connect a resistor between EN/ COMP and GND pins to adjust USB cable compensation Table 1 USB Cable Resistance Compensation Application Table ILOAD (mA) Figure 1 USB Cable Compensation at Various Resistor Divider Values VCOMP (mV)
5uP9601T-DS-F00A0, May 2018 www.upi-semi.com Functional Description Current Limit Protection The uP9601T continuously monitors the inductor current, w hen the inductor current is higher than current limit threshold, the current limit function activates and forces the upper switch to turn off to limit inductor current cycle by cycle. Output Short Circuit Protection The uP9601T provides output short circuit protection function. Once the output loader short-circuits, the SCP will be triggered and then always hiccup, the hiccup cycle time is set by an internal counter. When the SCP condition is removed or disappears, the converter will resume normal operation and the hiccup status will terminate. Output Over Voltage Protection The uP9601T provides output over voltage protection. Once the output voltage (measured the at SENSE- pin) gets higher than OVP threshold, the OVP will be triggered to shut down the converter. When the OVP condition disappears, the converter will resume normal operation and resume the normal state automatically. Over Temperature Protection The OTP is triggered and shuts down the uP9601T if the junction temperature is higher than 150oC The OTP is a non-latch type protection. The uP9601T automatically initiates another soft start cycle if the junction temperature drops below 130oC.
