PN7706SPC-R1 from Wuxi Chipown Micro electronics, in a SOP-8-EP. 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 | FAULT | output | Fault status output that is pulled to GND during undervoltage lockout, over-temperature, or output short-circuit events and returns to high impedance after recovery; it is rated 0 to 5.5 V in operation and -0.3 to 7 V absolute maximum. |
| 2 | IN1 | input | Input signal 1 that controls OUT1, compatible with 5 V and 3.3 V logic with VIH minimum 1.8 V and VIL maximum 0.5 V, operating range 0 to 5.5 V and absolute maximum -0.3 to 7 V. |
| 3 | IN2 | input | Input signal 2 that controls OUT2, compatible with 5 V and 3.3 V logic with VIH minimum 1.8 V and VIL maximum 0.5 V, operating range 0 to 5.5 V and absolute maximum -0.3 to 7 V. |
| 4 | ISET | passive | Drive current limit programming pin that may be left floating (3 A limit) or grounded (1.5 A limit), or connected to GND through a resistor between 27 kΩ and 120 kΩ to set a limit between 1.5 A and 3 A. |
| 5 | GND | power_in | Ground reference pin for the device, which must be connected to the ground plane of the load per the layout guidance. |
| 6 | OUT2 | output | H-bridge output 2 driving the motor, with an absolute maximum rating of -0.7 to 36 V. |
| 7 | OUT1 | output | H-bridge output 1 driving the motor, with an absolute maximum rating of -0.7 to 36 V. |
| 8 | VCC | power_in | Supply pin with an operating range of 2.7 V to 24 V and an absolute maximum rating of -0.3 to 36 V. |
| 9 | Thermal Pad | passive | Exposed heat-sink pad that should be soldered to the PCB top-layer ground pad to conduct heat away from the package, as recommended in the layout guidance. |
