  • The L9396 is an integrated power management System Basis Chip targeting a large spectrum of automotive electronics applications, in particular ABS, EPS and Transmission, compatible with single (12 V) battery system.

    It combines a switched mode power supply for pre-regulation along with 3 independent integrated linear regulators and a powerful configurable regulator for µC supply that can operate either in buck or linear mode with an external FET.
    The device also integrates a 4-channels flexible interface for Wheel Speed Sensor or tracking regulation, 2 configurable pre-drivers for fail safe and motor pump, 1 configurable general purpose outputs, wake-up detection circuitry, advanced fail-safe functionality, watchdog control and system monitoring.
    The boost regulator (optionally enabled) is intended to sustain cold cranking pulses, stop & start and weak battery conditions, while the buck pre-regulator drastically improves the power efficiency and CO2 emissions.
    Different combinations enable to supply the system microcontroller and external peripheral loads and sensors with wide current ranges and adjustable voltage levels.
    In addition, the L9396 provides enhanced system standby functionalities.
