PMIC – Gate Drivers refer to the application-specific integrated circuits (ASICs) used to manage power and control the power management in electrical systems. Among these ASICs is the FAN3223TMPX. It is part of the power management unit (PMU) which is responsible for generating and providing the auxiliary power needed by the device to operate efficiently.

Specifically, the FAN3223TMPX is an intelligent dual-channel gate driver with an ultra-low quiescent current consumption of only 0.3uA. It supports both single-ended and push-pull output configurations. Each channel has an independent enable/disable pin for fast and easy power control. It also provides protection from over-current conditions and a thermal shutdown of the gate drivers.

The FAN3223TMPX is designed for use in advanced power management systems used in consumer devices, such as smartphones and tablet PCs. It is optimized for use with MOSFET and IGBT driver stages. It supports voltage levels up to 28V, allowing it to be used for a variety of applications including high power converters, DC/DC converters, switched regulators, motor drivers and power switches.

The FAN3223TMPX provides excellent performance in terms of power efficiency, stability, and low noise. It has an operating temperature range of -40°C to +85°C and can be used over the entire automotive and industrial temperature ranges. Its low quiescent current draw and low voltage operation further ensure excellent overall performance in battery-powered systems.

The working principle of the FAN3223TMPX is based on the suppression of the capacitive transients due to the sudden switching of MOSFETs and IGBTs. It operates in two modes, normal and low-power. During normal operating mode, the FAN3223TMPX peak current is set to a certain value to minimize the voltage drop and limit the peak current. In low-power mode, the peak current is decreased to lower levels to reduce the overall power consumption.

The FAN3223TMPX provides a flexible and cost-effective solution for the power management needs of advanced consumer electronics applications. It offers a reliable and robust solution for high power switching and control applications in automotive, industrial and consumer electronics.
