MIC4421YM Description

Short technical summary and product information.

The MIC4421YM is a single-channel low-side gate driver designed by Microchip Technology for driving MOSFETs and IGBTs. It provides a peak output current of 6A for both source and sink, with a typical rise and fall time of 25ns. The device operates over a wide supply voltage range of 4.5V to 18V, making it suitable for various power management applications.

 

Key electrical characteristics include a low output impedance of 1.5Ω, a typical delay time of 30ns, and the ability to drive capacitive loads up to 47,000pF. The logic input is compatible with voltages from 0.8V (VIL) to 2.4V (VIH), and the input capacitance is typically 7pF. The supply current with a logic 1 input is 450µA.

 

The MIC4421YM is housed in an 8-pin SOIC package and is rated for a junction temperature range of -40°C to 150°C. This driver is suitable for switch-mode power supplies, motor controllers, and other power conversion circuits requiring high-speed, high-current gate drive.
