PMIC from STMicro feature CAN FD and LIN for automotive car-body controllers

The new power-management IC STMicroelectronics’ SPSB081 for car body controllers feature a main fixed-voltage low-dropout regulator (LDO), a secondary programmable LDO, four high-side drivers, a CAN FD transceiver , and an optional LIN transceiver . These power chips provide multiple standby modes with very low quiescent current and programmable local or remote wake-up to help minimize power consumption. Here are the more details shared by STMicroelectronics in it's release: The power sources and transceivers available on-chip help simplify the design of car-body controllers for a sunroof, seats, tailgate, doors, and lighting modules. Highlighting their adaptability, the controllers are also used in gateways, HVAC controllers, passive keyless entry systems, telematic control units, and control panels. The available variants include the SPSB081C3 and SPSB081C5, which contain a 3.3V or 5V fixed LDO, respectively, with one CAN transceiver. The SPSB0813 and SPSB0815 contain the additional LIN transceiver. The secondary LDO, included in all variants, can be programmed through the IC’s SPI port to operate as an independent 3.3V or 5V regulator, or to track the main LDO. The four high-side drivers can source up to 140mA to power LEDs and sensors, with current monitoring and a 10-bit PWM timer for each channel. Extensive built-in protection is provided, as well as a diagn...
