DRV8320H DRV8320S AGND 23 23 PWR Device analog ground. Connect to system ground. CPH 1 1 PWR Charge pump switching node. Connect a X5R or X7R, 47-nF, VM-rated ceramic capacitor between the CPH and CPL pins. CPL 32 32 PWR Charge pump switching node. Connect a X5R or X7R, 47-nF, VM-rated ceramic capacitor between the CPH and CPL pins. DVDD 24 24 PWR 3.3-V internal regulator output. Connect a X5R or X7R, 1-µF, 6.3-V ceramic capacitor between the DVDD and AGND pins. This regulator can source up to 30 mA externally. ENABLE 22 22 I Gate driver enable. When this pin is logic low the device enters a low power sleep mode. An 8 to 40-µs pulse can be used to reset fault conditions. GHA 5 5 O High-side gate driver output. Connect to the gate of the high-side power MOSFET. GHB 12 12 O High-side gate driver output. Connect to the gate of the high-side power MOSFET. GHC 13 13 O High-side gate driver output. Connect to the gate of the high-side power MOSFET. GLA 7 7 O Low-side gate driver output. Connect to the gate of the low-side power MOSFET. GLB 10 10 O Low-side gate driver output. Connect to the gate of the low-side power MOSFET. |
