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.
主要特性
- 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
