MAX20087ATPA from Analog Devices Inc Maxim Integrated, in a TQFN-20-EP(4x4). 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 PGND power_in Power ground; connect GND and PGND together to the exposed pad (EP).
2 IN power_in Camera supply input; connect to the output of the DC-DC converter feeding the cameras (3V to 15V input supply per features, IN to PGND absolute maximum -0.3V to +20V).
3 IN power_in Camera supply input; connect to the output of the DC-DC converter feeding the cameras (3V to 15V input supply per features, IN to PGND absolute maximum -0.3V to +20V).
4 IN power_in Camera supply input; connect to the output of the DC-DC converter feeding the cameras (3V to 15V input supply per features, IN to PGND absolute maximum -0.3V to +20V).
5 PGND power_in Power ground; connect GND and PGND together to the exposed pad (EP).
6 OUT1 power_out Protected camera supply output 1; connect a 1µF or larger ceramic capacitor from OUT1 to PGND.
7 OUT3 power_out Protected camera supply output 3; connect a 1µF or larger ceramic capacitor from OUT3 to PGND.
8 N.C. unconnected Not connected; leave unconnected or connect to ground.
9 GND power_in Analog ground; connect GND and PGND together to the exposed pad (EP).
10 ISET passive Output current-limit setting; connect a resistor from ISET to GND to set the per-channel current limit (adjustable 100mA to 600mA).
11 VDD power_in Device input supply (3.0V to 5.5V supply voltage range); connect a 100nF or larger ceramic capacitor from VDD to GND.
12 GND power_in Analog ground; connect GND and PGND together to the exposed pad (EP).
13 SDA bidirectional I2C data I/O.
14 SCL input I2C clock input.
15 EN input Active-high enable input; drive EN high for normal operation, where the rising edge starts soft-start on enabled channels and the falling edge turns them off.
16 ADDR input I2C address select; connect to ground or VDD to select between two different I2C addresses.
17 INT output Active-low, open-drain interrupt output; an external pullup resistor is required if used.
18 N.C. unconnected Not connected; leave unconnected or connect to ground.
19 OUT4 power_out Protected camera supply output 4; connect a 1µF or larger ceramic capacitor from OUT4 to PGND.
20 OUT2 power_out Protected camera supply output 2; connect a 1µF or larger ceramic capacitor from OUT2 to PGND.
21 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
