VNQ5050AKTR-E from STMICROELECTRONICS, in a SSOP-24. 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 VCC power_in Battery connection; operating range 4.5 to 36 V, absolute maximum 41 V, with active clamp at 41 to 52 V.
2 GND power_in Ground connection that must be reverse battery protected by an external diode/resistor network; DC reverse ground pin current is limited to 200 mA.
3 INPUT1 input Voltage controlled CMOS compatible input with hysteresis that controls the state of output 1 switch (VIL max 0.9 V, VIH min 2.1 V).
4 CURRENT SENSE1 output Analog current sense pin for channel 1 delivering a current proportional to the load current, high impedance when CS_DIS is high.
5 INPUT2 input Voltage controlled CMOS compatible input with hysteresis that controls the state of output 2 switch (VIL max 0.9 V, VIH min 2.1 V).
6 CURRENT SENSE2 output Analog current sense pin for channel 2 delivering a current proportional to the load current, high impedance when CS_DIS is high.
7 INPUT3 input Voltage controlled CMOS compatible input with hysteresis that controls the state of output 3 switch (VIL max 0.9 V, VIH min 2.1 V).

9 INPUT4 input Voltage controlled CMOS compatible input with hysteresis that controls the state of output 4 switch (VIL max 0.9 V, VIH min 2.1 V).
10 CURRENT SENSE4 output Analog current sense pin for channel 4 delivering a current proportional to the load current, high impedance when CS_DIS is high.
11 CS_DIS input Active high CMOS compatible pin that disables the current sense pins (VCSDL max 0.9 V, VCSDH min 2.1 V); sense enabled when low or open.
