POWER MANAGEMENT iC

Rev A1, Page 1/17

FEATURES

APPLICATIONS

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

Universal voltage supply iC with

monitoring and autarky function

for the voltage supply of auto-

motive and industrial applica-

tions

12V/30mA tri-state output

Low standby current of typ. 30µA

PACKAGE

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
