Next Generation Micro Controller Supply
TLE7368
1Overview
Features
High efficient next generation microcontroller power supply system
Wide battery input voltage range < 4.5 V up to 45 V
Operating temperature range
T
j = -40 °C to +150 °C
Pre-regulator for low all over power loss:
Integrated current mode Buck converter 5.5 V/2.5 A
Post-regulators, e.g. for system and controller I/O supply:
– LDO1: 5 V
±2%, 800 mA current limit
– LDO2: 3.3 V
±2% or 2.6V ±2% (selectable output), 700 mA
current limit
Integrated linear regulator control circuit to supply controller cores:
– LDO3 control for an external NPN power stage: 1.5 V
±2%
Post-regulators for off board supply:
– 2 Tracking regulators following the main 5 V, 105 mA and 50 mA
Stand-by regulator with lowest current consumption:
– Linear voltage regulator as stand-by supply for e.g.
memory circuits
– Hardware selectable output voltages as 1.0 V or 2.6 V, 30 mA
– Independent battery input, separated from Buck regulator input
Hardware controlled on/off logic
Undervoltage detection:
– Undervoltage reset circuits with adjustable reset delay time at power up
– Undervoltage monitoring circuit on stand-by supply
Window watchdog circuit
Overcurrent protection on all regulators
Power sequencing on controller supplies
Overtemperature shutdown
Packages: Low
