CM1602 from iCM(创芯微), in a SOP-8. 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 | GND | power_in | Ground pin (地); the datasheet gives no separate limit for this pin, and the VCC-to-GND and VD-to-GND ratings apply to it as the reference. |
| 2 | GND | power_in | Ground pin (地); the datasheet gives no separate limit for this pin, and the VCC-to-GND and VD-to-GND ratings apply to it as the reference. |
| 3 | GND | power_in | Ground pin (地); the datasheet gives no separate limit for this pin, and the VCC-to-GND and VD-to-GND ratings apply to it as the reference. |
| 4 | VCC | power_in | Chip power supply pin; the VCC-to-GND absolute maximum is -0.3 V to +7 V, and the UVLO turn-on is 1.5 V to 2.7 V (typical 2.1 V) with 0.3 V hysteresis. |
| 5 | VD | passive | Power MOSFET drain pin; the drain-to-GND absolute maximum is -0.7 V to +40 V, and BVDSS is 40 V minimum at VGS = 0 V, ID = 250 µA. |
| 6 | VD | passive | Power MOSFET drain pin; the drain-to-GND absolute maximum is -0.7 V to +40 V, and BVDSS is 40 V minimum at VGS = 0 V, ID = 250 µA. |
| 7 | VD | passive | Power MOSFET drain pin; the drain-to-GND absolute maximum is -0.7 V to +40 V, and BVDSS is 40 V minimum at VGS = 0 V, ID = 250 µA. |
| 8 | VD | passive | Power MOSFET drain pin; the drain-to-GND absolute maximum is -0.7 V to +40 V, and BVDSS is 40 V minimum at VGS = 0 V, ID = 250 µA. |
