U3502C

UNI SEMIC · Power Distribution Switches · ESOP-8

U3502C from UNI SEMIC, in a ESOP-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 VIN power_in Input supply; VIN supplies power to all of the internal control circuitries.
2 GND power_in Ground reference for the device.
3 EN input Enable input with a built-in resistance; the datasheet gives EN-on at 2.4 V minimum and 5 V maximum and EN-off at 1 V maximum, with 500 mV hysteresis.
4 TE passive TE pin; the datasheet gives no definition of its function in the pin description, so its role is not stated.
5 FB input Feedback input to the voltage hysteretic comparators, regulated to a 1.275 V typical feedback threshold.
6 VB power_out Positive power supply for the internal floating high-side MOSFET driver; connect a bypass capacitor between VB and SW.
7 SW output Switch node of the internal high-side power MOSFET.
8 IS input Current sensing input used for current detection.
9 VIN power_in Input supply; listed together with pin 1 as a VIN supply pin for all internal control circuitries.
