FEATURES Operating voltage range (VS) selectable output voltages: 3.3V ±2.0% Output current 150mA Reset impulse durations (10ms, 100ms) threshold levels programmable Selectable watchdog windows: Fixed: 37ms 75ms Variable: 50ms LIN-bus interface, specification Output slew rate control reduce Input voltage ranges from Wake Standby current <30µA typical Over temperature output current protection protected voltage level SO16 package external resistor between keeps internal power dissipation without compromising supply operation. Both 3.3V applications possible selecting output voltage with digital signal. precision feedback resistors required. APPLICATION interface Local Interconnect Network (LIN) communication including supervisory especially automotive applications reset output active (low) low, power power with watchdog timed out. reset threshold well reset impuls duration have programmable levels When active (high), voltage regulator turned output voltage available. quality regulated sensing with VCCS pin. regulator switched LINBus wake request directly Providing integrated watchdog with adjustable window duration offers best performance "System Basic Chip". DESCRIPTION used voltage regulator with integrated LIN-interface automotive applications. voltage regulator supplies application. PINNING Name VRES DRES RESW VCCS Description Battery supply Battery supply through external resistor (e.g. Ivcc=100mA) Reset threshold select, weak pull (VRES=H/L thresold high threshold low) Reset duration watchdog window select, weak pull (DRES=H/L reset duration 10ms 100ms) Transmitted serial data, pull Received serial data Ground LIN-Bus Reset output, active Reset additional output with threshold higher 200mV than threshold Watchdog input impulses from pull down Enable input, active high, pull down Wake LIN-Bus Voltage regulator output voltage mode, weak pull down (MOD=H/L->VCC=5V/3.3V) Output voltage sense input Voltage regulator output (VCC=5V 3.3V, Iload=0.100mA)
