INA381A1IDSGR

Texas Instruments · Power Management - Specialized · WSON-8-EP(2x2)

INA381A1IDSGR from Texas Instruments, in a WSON-8-EP(2x2). 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 IN+ input Connect this pin to the supply side of the shunt resistor
2 VS+ power_in Power supply: 2.7 V to 5.5 V
3 ALERT tri_state Overlimit alert, active low, open-drain output
4 RESET input Transparent or latch mode selection input
5 CMPREF input Input reference to the comparator
6 CMPIN input Signal input to the comparator
7 VOUT output Current-sense amplifier output voltage
8 IN- input Connect this pin to the load side of the shunt resistor
9 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
