ST’s New Automotive Power-Management Chip Reduces Car-Battery Load

Enables ultra-low standby current designs with fail-safe functionality and optimized system cost
Geneva /

Minimizing quiescent current consumption in today’s automotive electronic modules is critical for preserving the energy stored in the car battery. ST’s L99PM62XP advanced power-management IC provides a dedicated regulator with optimized dynamic behavior, enabling periodic system activation to monitor configurable wake-up sources, coupled with comprehensive diagnostic and system-status features.

Addressing increasing system complexity, ST’s new device integrates advanced fail-safe functionality to improve the sustainability and reliability of automotive electronic control units. The intrinsic fail-safe concept, including supervision of the microcontroller, supply voltages and temperatures, prevents the system from locking up under all imaginable failure conditions.

The integration of cost-efficient peripheral functions, such as high-side and low-side gate drivers, operational amplifiers and auxiliary regulators, reduces the number of external components, optimizing overall system cost.

The L99PM62XP offers compatibility with both LIN (Local Interconnect Network) and High-Speed CAN (Controller Area Network) automotive communication protocols for increased performance and versatility.

ST’s newest advanced power management IC targets microcontroller-based automotive applications such as door modules, body control units and mechatronic subsystems.

The L99PM62XP is in production, with unit pricing of $2 for volumes in the range of 1,000 pieces.
