Power management chip from ST Micro targeting microcontroller-based automotive apps

ST Micro has introduced the L99PM62XP, a new power management IC for car body applications. The L99PM62XP IC providing electronic control units with enhanced system power supply functionality including various standby modes, LIN and High-Speed CAN physical communication layers. The L99PM62XP also provides a fail-safe functionality with reduced external components, and targeting microcontroller-based automotive applications such as door modules, body control units and mechatronic subsystems.

The L99PM62XP IC contains two low drop voltage regulators to supply the system microcontroller and external peripheral loads such as sensors and provides enhanced system standby functionality with programmable local and remote wake up capability. In addition, five high-side drivers, two low-side drivers and two operational amplifiers increase the system integration level. The ST standard SPI interface (3.0) allows control and diagnosis of the device and enables generic software development.

The key features and benefits of the L99PM62XP power management IC are,

No electrolytic capacitor required on regulator outputs
Ultra low 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
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
