Datasheet Details

Part number:

A4933

Manufacturer:

Allegro

File Size:

1.12 MB

Description:

Automotive 3-Phase MOSFET Driver

Features

* ▪ High current 3-phase gate drive for large N-channel MOSFETs ▪ Pin compatible with Allegro A4935KJP ▪ Cross-conduction protection with adjustable dead time ▪ Top-off charge pump for 100% PWM ▪ Charge pump for low supply voltage operation ▪ Uncommitted current sense amplifier ▪ 5.5 to 50 V supply vo

Applications

* A unique charge pump regulator provides full (>10 V) gate drive for battery voltages down to 7 V and allows the A4933 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 pum
