TLE7368
Overview
The TLE7368 device is a multifunctional power supply circuit especially designed for Automotive powertrain systems using a standard 12 V battery. The device is intended to supply and monitor next ge.
- High efficient next generation microcontroller power supply system
- Wide battery input voltage range < 4.5 V up to 45 V
- Operating temperature range Tj = -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 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 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
