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. |
