PMIC – Gate Drivers are integrated circuits that control power MOSFETs and IGBTs. The ADP3654ARDZ-RL is a low-voltage, low-power gate driver for N-channel MOSFETs and IGBTs with integrated bootstrap diodes. It provides an efficient, monolithic, and low-cost solution for driving high current N-channel MOSFETs and IGBTs in a wide range of power management and motor control applications.

This device enables the gate of the MOSFET or IGBT to be controlled by a system controller employing very low voltages. It is capable of operating from a supply voltage range of 3.3V to 15V and provides an output current up to 600mA, making it suitable for driving high-current N-channel MOSFETs and IGBTs without the need for external gate drive circuits.

The ADP3654ARDZ-RL provides under-voltage protection and over-current protection to protect the system against unexpected faults. It also features a very low quiescent current of only 3.2µA, making it suitable for applications that require power efficiency.

The device has a wide range of applications, including power management and motor control. In power management applications, the device can be used to drive N-channel MOSFETs and IGBTs to control high-side switches, DC-DC converters, load switches, and OR’ing devices. In motor control applications, it can be used to drive N-channel MOSFETs and IGBTs to control power modules, motor drivers, and motor controls.

The working principle of the ADP3654ARDZ-RL is fairly simple. When an enable input is applied, the device sends a signal to the output that turns on the MOSFET or IGBT. The enable signal must be supplied from a system controller that is capable of operating at a voltage lower than the operating voltage of the MOSFET or IGBT. The bootstrap diode allows for the gate voltage of the MOSFET or IGBT to be raised to a level higher than the operating voltage. This allows for the device to be driven at very low voltages.

In addition, the bootstrap diode also helps to protect the device from any over-voltage spikes that may occur while the MOSFET or IGBT is turning off. This ensures that the device is reliable and safe to use in a wide range of applications.

The ADP3654ARDZ-RL provides an efficient, monolithic, and low-cost solution for driving high current N-channel MOSFETs and IGBTs. It has a wide range of applications, including power management and motor control, and features an integrated bootstrap diode for protection. The device can operate from a supply voltage range of 3.3V to 15V and provides an output current up to 600mA, making it an ideal solution for driving high-current N-channel MOSFETs and IGBTs.
