ACS712ELCTR-05B-T-JSM

JSMSEMI · Current Sensors · SOP-8

ACS712ELCTR-05B-T-JSM from JSMSEMI, in a SOP-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 sense terminal (positive). Pins 1 and 2 are internally tied together and form one side of the low-impedance primary current path. Tie pins 1 and 2 in parallel on the PCB to carry the measured current.
2 IP+ passive Primary current sense terminal (positive). Internally connected to pin 1. Combine with pin 1 on the PCB to reduce trace resistance and carry the full measured current.
3 IP- passive Primary current sense terminal (negative/return). Pins 3 and 4 are internally tied together and form the return side of the low-impedance primary current path. Tie pins 3 and 4 in parallel on the PCB.
4 IP- passive Primary current sense terminal (negative/return). Internally connected to pin 3. Combine with pin 3 on the PCB to reduce trace resistance.
5 GND power_in Signal ground. Reference for VCC and the analog output. Also serves as a programming pin during factory trim.
6 TEST input Factory test pin. Leave floating (unconnected) in normal application.
7 VOUT output Analog signal output. Ratiometric to VCC with a 0.5*VCC quiescent level (typ. 2.500 V at VCC=5 V) and 185 mV/A sensitivity for the -05B variant. Output swings from ~0.5 V (VOL) up to VCC-0.3 V (VOH); drive capability is 80 mA source / 40 mA sink. Recommended load: RL >= 4.7 kOhm and CL <= 1 nF.
8 VCC power_in Supply pin. Operating range 4.5 V to 5.5 V (typical 5 V), absolute max 6 V. Quiescent supply current typ. 11.18 mA. Bypass to GND with the CBYPASS capacitor as shown in the block diagram.
