ZXCT212BDW-7

Diodes Incorporated · Current Sense Amplifiers · SOT-363

ZXCT212BDW-7 from Diodes Incorporated, in a SOT-363. 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 REF input Analog reference voltage input, 0 to V+, which must be driven from a low-impedance circuit and kept within the absolute maximum rating.
2 GND power_in Ground connection for the device; the common-mode input range is specified down to GND - 0.3 V.
3 V+ power_in Power supply input, 2.7 V to 26 V.
4 IN+ input Analog input that connects to the supply side of the shunt resistor.
5 IN- input Analog input that connects to the load side of the shunt resistor.
6 OUT output Analog output voltage proportional to load current, following VOUT = (ILOAD x RSENSE) x GAIN + VREF.
