DRV8320HRTVR from Texas Instruments, in a WQFN-32-EP(5x5). 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 | CPH | power_in | Charge pump switching node; connect X5R or X7R 47nF capacitor between CPH and CPL rated for VM voltage with 2× safety margin. |
| 2 | VCP | power_out | Charge pump regulated output (VVM + 11V); connect X5R or X7R 1µF 25V ceramic capacitor between VCP and VM. |
| 3 | VM | power_in | Gate driver power supply input (6V to 60V); connect to motor power and VDRAIN with ≥10µF bulk capacitance and 0.1µF bypass. |
| 4 | VDRAIN | input | High-side MOSFET drain input; connect to common drain point of high-side MOSFETs and provides VDS overvoltage monitoring. |
| 5 | GHA | output | High-side gate driver output phase A; drives high-side MOSFET gate with peak currents up to 1A pull and 2A sink. |
| 6 | SHA | bidirectional | High-side source pin phase A; provides VDS monitoring input and high-side gate driver sink current output for phase A. |
| 7 | GLA | output | Low-side gate driver output phase A; drives low-side MOSFET gate with peak currents up to 1A pull and 2A sink. |
| 8 | SLA | input | Low-side source input phase A; connect to low-side MOSFET source and provides VDS monitoring input. |
| 9 | SLB | input | Low-side source input phase B; connect to low-side MOSFET source and provides VDS monitoring input. |
| 10 | GLB | output | Low-side gate driver output phase B; drives low-side MOSFET gate with peak currents up to 1A pull and 2A sink. |
| 11 | SHB | bidirectional | High-side source pin phase B; provides VDS monitoring input and high-side gate driver sink current output for phase B. |
| 12 | GHB | output | High-side gate driver output phase B; drives high-side MOSFET gate with peak currents up to 1A pull and 2A sink. |
| 13 | GHC | output | High-side gate driver output phase C; drives high-side MOSFET gate with peak currents up to 1A pull and 2A sink. |
| 14 | SHC | bidirectional | High-side source pin phase C; provides VDS monitoring input and high-side gate driver sink current output for phase C. |
| 15 | GLC | output | Low-side gate driver output phase C; drives low-side MOSFET gate with peak currents up to 1A pull and 2A sink. |
| 16 | SLC | input | Low-side source input phase C; connect to low-side MOSFET source and provides VDS monitoring input. |
| 17 | nFAULT | tri_state | Fault indicator open-drain output; pulled low during VM UVLO, charge pump UVLO, VDS OCP, GDF, or thermal shutdown; requires external pull-up resistor. |
| 18 | MODE | input | PWM mode selection input; 4-level input set by external resistor for 6x, 3x, 1x, or independent PWM control modes. |
| 19 | IDRIVE | input | Gate drive current setting; 7-level input set by external resistor selecting peak drive currents from 10mA to 1000mA pull and 20mA to 2000mA sink. |
| 20 | VDS | input | VDS overvoltage trip threshold; 7-level input set by external resistor for VDS protection threshold from 0.06V to 1.88V with adjustable degliching. |
| 21 | NC | unconnected | No internal connection; this pin can be left floating or connected to system ground. |
| 22 | ENABLE | input | Gate driver enable input; logic low enters low-power sleep mode drawing ≤20µA; 8µs to 40µs pulse resets latched faults without sleep. |
| 23 | AGND | power_in | Analog ground; connect to system ground; must be externally connected to PGND to avoid noise coupling. |
| 24 | DVDD | power_out | 3.3V internal regulator output; supplies internal logic and provides 30mA for external loads when bypassed with 1µF 6.3V capacitor. |
| 25 | INHA | input | High-side gate driver control input phase A; in 6x PWM mode controls high-side gate driver output state. |
| 26 | INLA | input | Low-side gate driver control input phase A; in 6x PWM mode controls low-side gate driver output state. |
