STMicroelectronics L99PM62GXP Power Management IC provides electronic control units with enhanced system power supply functionality. This includes various standby modes, LIN and HS CAN physical communication layers. The device's two low-drop voltage regulators supply the system microcontroller and external peripheral loads like sensors and provide enhanced system standby functionality with programmable local and remote wake-up capability.
Features
Two 5V voltage regulators for microcontroller and peripheral supply
No electrolytic capacitor required on regulator outputs
Ultralow quiescent current in standby modes
Programmable reset generator for power-on and undervoltage
Configurable window watchdog and fail-safe output
LIN 2.1 compliant (SAEJ2602 compatible) transceiver
Advanced HS CAN transceiver (ISO 11898-2/-5 and SAE J2284 compliant) with local failure and bus failure diagnosis
HS CAN transceiver supports partial networking
Complete 3-channel contact monitoring interface with programmable cyclic sense functionality
Programmable periodic system wake-up feature
ST SPI interface for mode control and diagnosis
5 fully protected high-side drivers with internal 4-channel PWM generator
2 low-side drivers with active Zener clamping
4 internal PWM timers
2 operational amplifiers with rail-to-rail outputs (VS) and low voltage inputs
Temperature warning and thermal shutdown
Applications
Automotive ECU's such as door zone and body control modules
