ATA6831C
Triple Half-bridge Driver with SPI and PWM
DATASHEET
Features
â Supply voltage up to 40V
â RDSon typically 0.8Ω at 25°C, maximum 1.5Ω at 150°C
â Up to 1.0A output current
â Three half-bridge outputs formed by three high-side and three low-side drivers
â Capable of switching loads such as DC motors, bulbs, resistors, capacitors, and
inductors
â PWM capability up to 25kHz for each high-side output controlled by external PWM
signal
â No shoot-through current
â Very low quiescent current IVS < 2µA in standby mode over total temperature range
â Outputs short-circuit protected
â Selective overtemperature protection for each switch and overtemperature
prewarning
â Undervoltage protection
â Various diagnostic functions such as shorted output, open load, overtemperature
and power-supply fail detection
â Serial data interface, daisy chain capable, up to 2MHz clock frequency
â QFN18 package
