L9952GXP Datasheet PDF - ST Microelectronics

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.

●Key Features

● 1 High side driver Out_HS ( RDSon,typ = 1 )

● 4 High side drivers for e.g. LED or HALL (RDSon,typ = 7 )

● Outputs are short circuit protected

● 2 Relay drivers ( RDSon,typ = 2 )

● Temperature warning and thermal shutdown

● 2 Op amp"s for current sensing in GND return lines

● 24 bit SPI interface for mode control and diagnostic

● LIN 2.1 compliant (SAEJ2602 compatible) transceiver

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

● Window watchdog and fail-safe output

● Low stand-by current: VBAT stby, 7μA; ,V1 stby, 45μA, (75μA in cycl. sense)

● Wake-up logic with cyclic contact monitoring

● Output drivers

● Interrupt output
