A4939 Datasheet - Allegro

Automotive Three Phase MOSFET Driver

A4939 Features

* High current 3-phase gate drive for N-channel MOSFETs

* Cross-conduction protection

* 5.5 to 50 V supply voltage range

* Regulated logic supply voltage output option

* Motor phase short to supply and short to ground detection

* Undervoltage, overtemp

A4939 General Description

The A4939 is a three-phase controller for use with N-channel external power MOSFETs and is specifically designed for automotive applications. A unique charge pump regulator provides full (>10 V) gate drive at battery voltages down to 7 V and allows the A4939 to operate with reduced gate drive at bat.
