Product details

Description

The A4919 is a three-phase controller for use with N-channel external power MOSFETs.

A unique charge pump regulator provides full (>10 V) gate drive at power supply voltages down to 7 V and allows the A4919 to operate with reduced gate drive at power supply voltages down to 5.5 V.

Features

High-current 3-phase gate drive for N-channel MOSFETs.
5.5 to 50 V supply voltage range.
Regulated logic supply voltage output option.
Low-current Sleep mode option.
Motor phase short-to-supply and short-to-ground detection.
Cross-conduction protection.
Undervoltage, overtemperature monitors.
