ZXCT1082QE5TA

Diodes Incorporated · Current Sense Amplifiers · SOT-25

ZXCT1082QE5TA 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 OUT output Output pin that gives a current output on the ZXCT1082Q/83Q and a voltage output on the ZXCT1084Q/85Q/86Q/87Q, with an output voltage range of 0 to VS- -1 V (Note 5).
2 GND power_in Ground pin of the device.
3 S+ input Positive input of the current monitor with a wide common-mode input range and input current limited to ±12 mA; on the ZXCT1082Q/83Q an external resistor RGT connects S+ to the supply side (VSUPPLY) of the sense resistor, while on the ZXCT1084Q/85Q/86Q/87Q it connects directly to VSUPPLY.
4 S- input Negative input of the current monitor with a wide common-mode input range and input current limited to ±12 mA; on the ZXCT1082Q/83Q an external resistor RGT connects S- to the load side (VLOAD) of the sense resistor, while on the ZXCT1084Q/85Q/86Q/87Q it connects directly to VLOAD.
5 VCC power_in Analogue supply pin that powers the internal circuitry, with a supply voltage range of 2.7 V to 60 V for the ZXCT1082Q/84Q/86Q and 2.7 V to 40 V for the ZXCT1083Q/85Q/87Q.
