ACS711KLCTR-25AB-T

Allegro MicroSystems LLC · Current Sensors · SOIC-8

ACS711KLCTR-25AB-T from Allegro MicroSystems LLC, in a SOIC-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 IP+ passive Primary current input terminal. Terminals for the current being sensed; fused internally with pin 2. The IP+ and IP− pairs form the isolated copper conduction path with ~1.2 mΩ resistance in the LC package.
2 IP+ passive Primary current input terminal. Terminals for the current being sensed; fused internally with pin 1.
3 IP- passive Primary current output terminal. Terminals for the current being sensed; fused internally with pin 4.
4 IP- passive Primary current output terminal. Terminals for the current being sensed; fused internally with pin 3.
5 GND power_in Signal ground terminal. Low-side reference for VCC, VIOUT, and FAULT.
6 FAULT output Overcurrent fault output; active-low, open-drain style requiring an external pull-up (RPU ≥ 1 kΩ). Latches low when
7 VIOUT output Analog output signal. Ratiometric to VCC with quiescent output VCC/2 at IP = 0 A; sensitivity 55 mV/A for the x25AB variant. Bandwidth 100 kHz; drives loads ≥15 kΩ and ≤1 nF.
8 VCC power_in Device power supply terminal. 3 to 5.5 V single supply (3.3 V nominal for factory-trimmed accuracy); ICC ≈ 4 mA typical. Bypass with 0.1 μF to GND. Absolute max 7 V.
