CJDR9110T from Changjing, in a ESOP8. 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 1 | output | H-bridge output 1, which drives the motor; the datasheet rates continuous output current at up to 1.5 A and peak output current at 2.5 A. |
| 2 | VM | power_in | Logic and motor power supply input; the recommended load supply range is 3.8 V to 12 V and the absolute maximum is 17 V. |
| 3 | VM | power_in | Logic and motor power supply input, shared with pin 2; the recommended load supply range is 3.8 V to 12 V and the absolute maximum is 17 V. |
| 4 | OUT 2 | output | H-bridge output 2, which drives the motor; the datasheet rates continuous output current at up to 1.5 A and peak output current at 2.5 A. |
| 5 | GND | power_in | Device ground that must be connected to system ground. |
| 6 | IN 2 | input | H-bridge PWM control input 2; logic input is rated 0 to 5.0 V (absolute maximum -0.5 to 7.0 V) and includes an internal 100 kΩ pull-down to low. |
| 7 | IN 1 | input | H-bridge PWM control input 1; logic input is rated 0 to 5.0 V (absolute maximum -0.5 to 7.0 V) and includes an internal 100 kΩ pull-down to low. |
| 8 | GND | power_in | Device ground, shared with pin 5, that must be connected to system ground. |
| 9 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
