WS4683C

The WS4683C is a Type-C PD load switch with programable precision current limit. WS4683C has VIN under voltage lockout, output over voltage protection, reverse current protection, over current protection and over temperature protection. The over current protection threshold is set by an external resistor from ILIM pin, ranged from 400 mA to 3.3A. The output current will be clamped at threshold if load current hit the current limit. WS4683C will assert/FLT pin to low with an 11 ms deglitch time after over current protection triggers. FO pin is used to program the power on slow rate for VBUS, which will be 2 ms soft start if FO is pulled to GND. Such function can be disabled by pulling FO pin to high. Fast RCP recovery circuit is also implemented, with the help of witch the switch will turn on within 20 μs once it exits reverse condition.
