ACS37612LLUALU-010B5

Allegro MicroSystems, LLC · Current Sensors · TSSOP-8

ACS37612LLUALU-010B5 from Allegro MicroSystems, LLC, in a TSSOP-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 VOUT output Analog output signal that varies linearly with the bidirectional AC or DC field sensed, also used for programming.
2 GND power_in Ground pin.
3 NC unconnected Not connected; tie to GND for optimal ESD performance.
4 VCC power_in Input power supply, also used for programming; the part operates from a 3.3 V or 5.0 V single supply.
5 NC unconnected Not connected; tie to GND for optimal ESD performance.
6 NC unconnected Not connected; tie to GND for optimal ESD performance.
7 NC unconnected Not connected; tie to GND for optimal ESD performance.
8 NC unconnected Not connected; tie to GND for optimal ESD performance.
