Texas Instruments · Brushless DC (BLDC) Motor Driver · WQFN-32-EP(5x5)

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.

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.
