DRV8803DWR from Texas Instruments, in a SOIC-20-300mil. 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 | VM | power_in | Device power supply voltage input, operating range 8.2V to 60V for motor or inductive load supply |
| 2 | VCLAMP | passive | Catch diode clamp voltage connection point for inductive load energy dissipation; connect to VM supply or external Zener/TVS diode to VM |
| 3 | OUT1 | output | Low-side switch output for channel 1 connected to load 1; drives low when IN1 = 1, maximum output voltage 65V |
| 4 | OUT2 | output | Low-side switch output for channel 2 connected to load 2; drives low when IN2 = 1, maximum output voltage 65V |
| 5 | GND | power_in | Device ground connection; all ground pins must be grounded |
| 6 | GND | power_in | Device ground connection; all ground pins must be grounded |
| 7 | GND | power_in | Device ground connection; all ground pins must be grounded |
| 8 | OUT3 | output | Low-side switch output for channel 3 connected to load 3; drives low when IN3 = 1, maximum output voltage 65V |
| 9 | OUT4 | output | Low-side switch output for channel 4 connected to load 4; drives low when IN4 = 1, maximum output voltage 65V |
| 10 | nENBL | input | Active-low output enable input; internal pull-down resistor (100kΩ typical); low enables all four output drivers |
| 11 | RESET | input | Active-high reset input to reset internal logic and overcurrent protection circuit; internal pull-down resistor (100kΩ typical) |
| 12 | IN4 | input | Channel 4 logic input; IN4 = 1 drives OUT4 low; internal pull-down resistor (100kΩ typical) |
| 13 | IN3 | input | Channel 3 logic input; IN3 = 1 drives OUT3 low; internal pull-down resistor (100kΩ typical) |
| 14 | GND | power_in | Device ground connection; all ground pins must be grounded |
| 15 | GND | power_in | Device ground connection; all ground pins must be grounded |
| 16 | GND | power_in | Device ground connection; all ground pins must be grounded |
| 17 | IN2 | input | Channel 2 logic input; IN2 = 1 drives OUT2 low; internal pull-down resistor (100kΩ typical) |
| 18 | IN1 | input | Channel 1 logic input; IN1 = 1 drives OUT1 low; internal pull-down resistor (100kΩ typical) |
| 19 | NC | unconnected | No connect pin; leave unconnected |
| 20 | nFAULT | tri_state | Active-low open-drain fault output indicating overcurrent protection trip, thermal shutdown, or UVLO condition; maximum 20mA, external pull-up resistor required |
