Multi-Channel Half-Bridge Drivers for Automotive and Industrial Applications
Features
- Supply and operation up to 40V
- RDSon maximum 1.5–1.8Ω
- Up to 650mA–1A load current
- Three or six half-bridge outputs
- Capable of switching all kinds of loads such as DC motors, bulbs, resistors, capacitors and inductors
- PWM capability up to 25 kHz for each half bridge output controlled by external PWM signal (ATA6831C, ATA6832C)
- No shoot-through current
- Very low quiescent current < 2 µA in Standby Mode versus total temperature range
- Outputs short circuit protected
- Overtemperature prewarning and protection for each output stage
- Selective thermal shutdown for every single output stage (ATA6831C, ATA6832C)
- Maximum junction temperature up to 200°C (ATA6832C)
- Undervoltage protection
- Various diagnostic functions such as shorted out, open-load, overtemperature and power-supply fail detection
- SPI interface, daisy chain capable
