Power Management System 36-Pin PowerSSO T/R

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.

Two 5V low-drop voltage regulators (250mA, 100mA continuous mode

Low stand-by current: V_BAT 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 (R_DSon,typ = 7 )

1 High side driver Out_HS ( R_DSon,typ = 1 )

2 Relay drivers ( RDSon,typ = 2 )

Outputs are short circuit protected
