L9952GXP - Power Management

General Description

The L9952GXP is a power management system IC containing two low drop regulators with advanced contact monitoring and additional peripheral functions.

The integrated standard serial peripheral interface (SPI) controls all L9952GXP operation modes and provides driver diagnostic functions.

Table 1.

Key Features

  • Two 5V low-drop voltage regulators (250mA, 100mA continuous mode.
  • Low stand-by current: VBAT stby, 7µA; ,V1 stby, 45µA, (75µA in cycl. sense).
  • Window watchdog and fail-safe output.
  • Interrupt output.
  • Wake-up logic with cyclic contact monitoring.
  • LIN 2.1 compliant (SAEJ2602 compatible) transceiver.
  • 24 bit SPI interface for mode control and diagnostic.
  • Output drivers.
  • 4 High side drivers for e. g. LED or HALL (RDSon,typ = 7 Ω ).
  • 1 High side driver O.
