Power Management Specialized BODY SYSTEM ICS
Description:
The is a monolithic integrated circuit in an exposed pad VQFN-48 7mm x 7mm power package with Lead Tip Inspection LTI feature to support Automatic Optical Inspection AOI. The device is designed for various CAN automotive applications as main supply for the microcontroller and as interface for a CAN bus network.
To support these applications, the System Basis Chip SBC provides the main functions, such as a 5V lowdropout voltage regulator LDO for e.g. a microcontroller supply, another 5V low-dropout voltage regulator with off-board protection for e.g. sensor supply, another 5V/3.3V regulator to drive an external PNP transistor, which can be used as an independent supply for off-board usage or in load sharing configuration with the main regulator VCC1, a HS-CAN transceiver supporting CAN FD for data transmission, high-side switches with embedded protective functions and a 16-bit Serial Peripheral Interface SPI to control and monitor the device. Also implemented are a configurable timeout / window watchdog circuit with a reset feature, three Fail Outputs and an under voltage reset feature.
The device offers low-power modes in order to minimize current consumption on applications that are connected permanently to the battery. A wake-up from the low-power mode is possible via a message on the buses, via the bi-level sensitive monitoring/wake-up inputs as well as via cyclic wake. The device is designed to withstand the severe conditions of automotive applications.
