DRV8662RGPT from Texas Instruments, in a QFN-20-EP(4x4). 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 | VPUMP | power_out | Internal charge pump output voltage; requires 0.1µF X5R or X7R capacitor to ground for stability |
| 2 | VDD | power_in | Power supply input; operating range 3.3V to 5.5V |
| 3 | FB | input | Boost feedback input; programs VBST from 15V to 105V via external resistor divider |
| 4 | GND | power_in | Ground return path |
| 5 | GND | power_in | Ground return path |
| 6 | GND | power_in | Ground return path |
| 7 | SW | power_out | Boost converter switch node; connects to 3.3µH to 22µH external inductor for boost energy transfer |
| 8 | SW | power_out | Boost converter switch node; connects to 3.3µH to 22µH external inductor for boost energy transfer |
| 9 | NC | unconnected | No connect pin; leave floating |
| 10 | VBST | power_out | Boost converter output voltage; programmable range 15V to 105V maximum |
| 11 | VBST | power_out | Boost converter output voltage; programmable range 15V to 105V maximum |
| 12 | PVDD | power_in | Amplifier supply voltage from boost converter; operates 15V to 105V |
| 13 | OUT+ | output | Non-inverting differential output for piezo actuator; maximum 200VPP with 100nF load at 300Hz |
| 14 | OUT- | output | Inverting differential output for piezo actuator; maximum 200VPP with 100nF load at 300Hz |
| 15 | REXT | input | Current limit resistor to ground; range 6kΩ to 35kΩ programs boost peak current limit |
| 16 | IN- | input | Inverting analog input; 1.8V peak input for gain-matched output operation; if unused connect to GND through capacitor |
| 17 | IN+ | input | Non-inverting analog input; 1.8V peak input for gain-matched output operation; if unused connect to GND through capacitor |
| 18 | GAIN0 | input | Gain programming LSB; combined with GAIN1 sets amplifier gain to 28.8dB, 34.8dB, 38.4dB, or 40.7dB |
| 19 | GAIN1 | input | Gain programming MSB; combined with GAIN0 sets amplifier gain to 28.8dB, 34.8dB, 38.4dB, or 40.7dB |
| 20 | EN | input | Chip enable input; logic high enables boost and amplifier with 1.5ms typical startup time |
| 21 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
