A4910

Automotive 3-Phase MOSFET Driver

Description

Features and Benefits

The A4910 is a three-phase controller for use with N-channel

external power MOSFETs and is specifically designed for

automotive applications.

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

• 3-phase current sense amplifiers

• SPI-compatible serial or direct parallel control

• Cross-conduction protection

• Programmable dead time

• Top-off charge pump for 100% PWM

• Uncommitted buffer amplifier

A unique charge-pump regulator provides full (>10 V) gate

drive for battery voltages down to 7 V, and allows the A4910

to operate with a reduced gate drive down to 5.5 V.

A bootstrap capacitor is used to provide the above battery

supply voltage required for N-channel MOSFETs.An internal

charge pump for the high-side drive allows DC (100% duty

cycle) operation.

• 5.5 to 50 V supply voltage range

• CMOS inputs, 3.3 to 5 V logic supply

• Extensive diagnostics output

• Low-current sleep mode

Full control over all six power MOSFETs in the 3-phase

bridge is provided, allowing motors to be driven with block

commutationorsinusoidalexcitation.ThepowerMOSFETsare

protected from shoot-through by integrated crossover control

and programmable dead time.

PACKAGE:

48-pin LQFP with exposed thermal pad (suffix JP)
