A4900
Description
The A4900 is a high-voltage, high-speed, power IGBT or MOSFET driver providing three independent half-bridge channels for three-phase 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.
Key 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
- Undervoltage detection
- Overcurrent detection with integrated fault blanking
- Overtemperature shutdown
- Matched propagation delays
