Texas Instruments · Motor Driver ICs · HVQFN-32-EP(5x5)

DRV8702QRHBRQ1 from Texas Instruments, in a HVQFN-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 GND power_in Device ground connection point.
2 IN1/PH input Input control pin whose logic function depends on MODE pin setting; internally connected to pull-down resistor.
3 IN2/EN input Input control pin whose logic function depends on MODE pin setting; internally connected to pull-down resistor.
4 GND power_in Device ground connection point.
5 IDRIVE input Gate driver current setting pin; applied resistance or voltage sets gate drive peak source and sink currents.
6 VDS input VDS over-current monitor threshold setting pin; applied resistance adjusts VDS(OCP) threshold voltage for per-FET protection.
7 GND power_in Device ground connection point.
8 nSLEEP input Device sleep mode control; logic low enables low-power sleep mode with all FETs in high-impedance state; internally connected to pull-down resistor.
9 GND power_in Device ground connection point.
10 nFAULT tri_state Fault indicator output; pulled to logic low when fault condition detected; open-drain output requiring external pull-up resistor.
11 MODE input Mode control pin; pull low for H-bridge mode, high for independent half-bridge mode, or leave floating for PWM mode; mode is latched on power-up or sleep exit; internally connected to pull-up and pull-down resistors.
12 DVDD power_out 3.3V regulated logic supply output for internal digital circuits; bypass to ground with 6.3V 1µF ceramic capacitor.
13 GND power_in Device ground connection point.
14 AVDD power_out 5V regulated analog supply output for current amplifier and sensing circuits; bypass to ground with 6.3V 1µF ceramic capacitor.
15 VREF power_in Current reference input voltage; sets PWM chopper current regulation level for motor current limiting.
16 SO output Current amplifier output; voltage proportional to sensed current with gain AV ≈20V/V; do not place capacitance exceeding 1nF on this pin.
17 GND power_in Device ground connection point.
18 GH1 output High-side gate driver output for bridge 1; connect to gate of high-side NMOS FET Q(HS1).
19 SH1 input High-side source node connection for bridge 1; connect to source of high-side FET Q(HS1); used for VDS monitoring.
20 GL1 output Low-side gate driver output for bridge 1; connect to gate of low-side NMOS FET Q(LS1).
21 SP input Current sense amplifier positive input; connect to high side of external current sense resistor.
22 SN input Current sense amplifier negative input; connect to low side of external current sense resistor for over-current detection.
23 SL2 input Low-side source node connection for bridge 2; connect to source of low-side FET Q(LS2); used for VDS monitoring.
24 GL2 output Low-side gate driver output for bridge 2; connect to gate of low-side NMOS FET Q(LS2).
25 SH2 input High-side source node connection for bridge 2; connect to source of high-side FET Q(HS2); used for VDS monitoring.
26 GH2 output High-side gate driver output for bridge 2; connect to gate of high-side NMOS FET Q(HS2).
27 VDRAIN input High-side FET drain connection node; common connection point where high-side FET drains connect; shared between H-bridge channels.
28 VM power_in Motor power supply input (5.5V to 45V); requires 0.1µF ceramic bypass and minimum 10µF bulk capacitors to ground for EMI filtering.
29 VCP power_out Charge pump output for high-side gate drive voltage; connect 16V rated 1µF ceramic capacitor between VCP and VM pins.
30 CPH output Charge pump high switching node; connect 0.1µF X7R ceramic capacitor (rated for VM voltage) between CPH and CPL pins.
31 CPL output Charge pump low switching node; connect 0.1µF X7R ceramic capacitor (rated for VM voltage) between CPH and CPL pins.
32 NC unconnected No connection; no internal connection; leave unconnected or tied to ground optionally.
33 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
