STMicroelectronics L9952GXP Power Management System IC Datasheet
The L9952GXP is a Power Management System (PMS) integrated circuit designed primarily for automotive Electronic Control Units (ECUs), such as door zone and body control modules. The device integrates two low-drop voltage regulators (V1 and V2) with advanced contact monitoring capabilities to ensure system reliability.
Key features include a LIN 2.1 compliant transceiver, a 24-bit SPI interface for mode control and diagnostics, and multiple output drivers including four high-side drivers, one high-side driver, two relay drivers, and operational amplifiers for current sensing. The IC also incorporates protection mechanisms such as window watchdogs, failsafe outputs, thermal shutdown, and temperature warning.
