Overview

The AMT49101KJPTR-A-3 is a highly integrated N-channel MOSFET gate driver designed to control three-phase brushless DC (BLDC) motors. Operating from a wide supply range of 10V to 80V, it features an SPI interface for comprehensive diagnostics and parameter configuration, along with a 3.3V logic interface.

Why Choose This Part

This driver integrates high-side and low-side gate drives with an internal charge pump to ensure full gate drive for battery voltages down to 10V. It minimizes power consumption with a low 10uA sleep current and offers extensive diagnostic monitoring of MOSFET and system health via SPI.

Applications

Automotive Power Pumps
Ideal for oil, water, and fuel pump systems requiring high reliability and high-voltage automotive battery compatibility.
Electric Power Steering
Provides the precision gate drive and diagnostic feedback necessary for safety-critical EPS motor control.
Industrial Fans and Blowers
Supports high-voltage industrial BLDC motor control with minimal external components for space-constrained designs.
