POWER MANAGEMENT iC
FEATURES
° Supply voltage range of VBAT= 6 to 16.5V
° Autarky function to maintain temporarily output voltages with
breakdown of supply voltage
° Adjustable 200mA boost converter (VA1= VBAT+2V to 48V)
° 6V step-down regulator with integrated 125kHz oscillator
° Two downstream 5V linear regulators with 200mA/60mA
output current
° 12V/30mA tri-state output
° Low standby current of typ. 30µA
° Integrated high/low-side drivers e.g. to attach indicator lamps
° Overtemperature shutdown of high- and low-side drivers
° Undervoltage detection
° Serial single-wire communication interface
° Watchdog for monitoring of the external µ-controller
° CMOS-compatible inputs
° TTL-/CMOS-compatible outputs
° ESD protection
Rev A1, Page 1/17
