With the proliferation of electronics in today‘s cars and the ever-increasing power consumption, automakers need to reduce standby current consumption (quiescent current), and ST‘s automotive power management chip L99PM62XP can help overcome this challenge. In addition, the device provides complete fail-safe protection, which reduces the number of peripheral components and optimizes the overall cost of the system.

Minimizing the quiescent current consumption of automotive electronic modules is critical to preserving the car battery‘s charge. ST‘s L99PM62XP advanced power management IC is a purpose-built voltage regulator optimized for dynamic characteristics that periodically activates the system to monitor configurable wake-up resources, as well as full diagnostics and system status monitoring.

To address the increasing complexity of systems, ST‘s L99PM62XP integrates advanced fail-safe protection features to improve the continuous operation and reliability of automotive electronic control units. The inherent fail-safe concept includes monitoring of the microcontroller, supply voltage and temperature, preventing the system from locking up under all conceivable failure conditions.

The L99PM62XP integrates many cost-effective peripheral functions, such as upper and lower side drivers, operational amplifiers and auxiliary voltage regulators, which can reduce the number of external components and optimize the overall cost of the system.

The L99PM62XP is compatible with LIN and high-speed CAN automotive communication protocols, enabling higher transmission performance and versatility.

ST‘s advanced power management chip, the L99PM62XP, targets microcontroller-based automotive electronics applications such as door modules, body control units and electromechanical subsystems.
