ZXCT213QCDW-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 | Reference voltage input, 0 to V+, must be connected to a low-impedance circuit and not exceed GND - 0.3V to (V+) + 0.3V. |
| 2 | GND | power_in | Ground. |
| 3 | V+ | power_in | Power supply, 2.7V to 26V. |
| 4 | IN+ | input | Analog input connected to the supply side of the shunt resistor; common-mode range -0.3V to 26V. |
| 5 | IN- | input | Analog input connected to the load side of the shunt resistor; common-mode range -0.3V to 26V. |
| 6 | OUT | output | Analog output voltage proportional to load current, swinging GND - 0.3V to (V+) + 0.3V absolute maximum. |
