iCM(创芯微) · IC · SOP-8
CM1632CB 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 groups pins 1 and 2 as GND and gives no separate limit for this pin. |
| 2 | GND | power_in | Ground pin (地); the datasheet groups pins 1 and 2 as GND and gives no separate limit for this pin. |
| 3 | VCC | power_in | Chip power supply pin; the absolute maximum rating for VCC to GND is -0.3 V to 9 V. |
| 4 | VIN | power_in | Supply input pin (供电输入); the absolute maximum rating for VIN is -0.7 V to 32 V. |
| 5 | VD | passive | Power MOSFET drain pin; the drain-to-ground withstand is -0.7 V to 100 V. |
| 6 | VD | passive | Power MOSFET drain pin; the drain-to-ground withstand is -0.7 V to 100 V. |
| 7 | VD | passive | Power MOSFET drain pin; the drain-to-ground withstand is -0.7 V to 100 V. |
| 8 | VD | passive | Power MOSFET drain pin; the drain-to-ground withstand is -0.7 V to 100 V. |
