Next Generation Micro Controller Supply
TLE7368
1
Overview
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% at TLE7368G and TLE7368E
– 1.2 V ±2% at TLE7368-2E
– 1.3 V ±2% at TLE7368-3E
• 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 R_thja Power-P-DSO-36; small exposed pad PG-DSO-36
• PG-DSO-36 only: Green Product (RoHS compliant)
• AEC Qualified
