Description: High Voltage Three Phase Gate Driver

Features

* High voltage 3-phase gate drive
* Floating high-side gate drive to 550 VDC supply
* Tolerant to high voltage slew rates
* Cross-conduction protection with fixed dead time
* 15 V gate drive supply voltage
* TTL compatible logic inputs
* Underv

Applications

* A bootstrap capacitor is used to provide the above battery supply voltage required for N-channel MOSFETs or IGBTs used as high current switches. Direct control over all six gate drives in the 3-phase bridge is provided, allowing motors to be driven with block commutation or sinusoidal excitation. T
