ZXCT1110W5-7

Diodes Incorporated · Current-Sensing Amplifiers · SOT-25

ZXCT1110W5-7 from Diodes Incorporated, in a SOT-25. 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 NC unconnected No connection.
2 GND power_in Ground pin and substrate connection.
3 OUT output Current output pin; output voltage range is 0 to VS- - 1 V for 0 ≤ VSENSE ≤ 100mV, and absolute maximum is -0.3 to VS+ relative to GND.
4 S+ power_in Positive input of the current monitor with 2.5V to 36V common-mode range that also acts as the analog supply for internal circuitry; absolute maximum -0.3 to 40V relative to GND.
5 S- input Negative input of the current monitor with 2.5V to 36V wide common-mode input range; absolute maximum -0.3 to 40V relative to GND.
