The MIC4421ACT is a gate driver for PMIC - Gate Drivers applications. It is a low-side gate driver with active low enables. Its main building blocks are gate drivers, low-side switches, gate-drive-on resistors, and a power-on Reset (POR) circuit.The MIC4421ACT\'s gate driver provides three channels of low-side gate-drive current to efficiently drive two low-side external MOSFETs and one low-side N-channel power MOSFET. This gate driver offers a low-impedance output high sink current of up to +/-12V. It also has an adjustable output voltage range and can drive up to 15V high-side MOSFETs.The low-side switches provide gate-drive current to the external MOSFETs and N-channel power MOSFETs for quickly switching them on and off. The gate-drive-on resistors provide a constant current to the gate of the MOSFET that is on and a cutoff current to the gate when the MOSFET is turned off.The MIC4421ACT also features the Gate Saver circuit, which provides protection from over-voltage and over-current fault conditions. It will limit the driver output current to a safe value. This circuit also detects short-circuit conditions and then shuts down the gate drivers to prevent any further damage.The MIC4421ACT also has a built-in POR circuit, which prevents damage to the system due to high voltage conditions, as well as protects all MOSFETs from turning on in an over-voltage condition. It is designed to provide a complete low-side gate-drive solution, including over-voltage protection, over-current protection, and a self-test capability.In conclusion, the MIC4421ACT is a low-side gate driver solution for PMIC - Gate Drivers applications. It provides three channels of low-side gate-drive current to efficiently drive two low-side MOSFETs and one low-side N-channel power MOSFET. It also features a Gate Saver circuit, which provides protection from over-voltage and over-current fault conditions, and a POR circuit, which prevents damage to the system due to high voltage conditions.
