Device analog ground. Connect to system ground.
Charge pump switching node. Connect a X5R or X7R, 47-nF, VM-rated ceramic capacitor between the CPH and CPL pins.
Charge pump switching node. Connect a X5R or X7R, 47-nF, VM-rated ceramic capacitor between the CPH and CPL pins.
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.
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.
High-side gate driver output. Connect to the gate of the high-side power MOSFET.
High-side gate driver output. Connect to the gate of the high-side power MOSFET.
High-side gate driver output. Connect to the gate of the high-side power MOSFET.
Low-side gate driver output. Connect to the gate of the low-side power MOSFET.
Low-side gate driver output. Connect to the gate of the low-side power MOSFET.
(1) PWR = power, I = input, O = output, NC = no connection, OD = open-drain
