STMICROELECTRONICS SPSB0813-TR Power Management IC, 3.3 V Supply, -40 °C to 125 °C, QFN-EP-32

SPSB0813-TR is an automotive power management IC with LIN and CAN-FD. It is a power management system IC providing electronic control modules with enhanced power management functionality, including various standby modes to minimize power consumption with programmable local and remote wake-up capability, as well as LIN and CAN FD physical communication layers. The device has one low-drop voltage regulator to supply the system microcontroller and one voltage tracker to supply external peripheral loads such as sensors. Moreover, the device features four high-side drivers to supply LEDs and sensors. All outputs are short-circuit (SC) protected and implement open-load diagnosis. Typical applications are body control modules (BCM), gateway applications, telematic control unit, passive keyless entry and start modules, control panel, heating, ventilation and air conditioning (HVAC), seat control modules, sunroof modules, steering column, fuel pump.

• Minimum current limitation of 450mA for V1 and 400mA for V2
• No electrolytic capacitor required on regulator outputs, configurable window watchdog
• Very low quiescent current in standby modes (typ. 15µA)
• Programmable reset generator for power-on and undervoltage
• Programmable periodic system wake-up feature, thermal cluster
• STM standard serial peripheral interface (32Bit/ST-SPI)
• Internal 10-bit PWM timer for each standalone high-side driver
• Buffered supply for all voltage regulators, DIAGN output pin for fail-safe signalization
• Current monitor output for all internal high-side drivers, open-load diagnosis for all outputs
• AEC-Q100 qualified, device contains temperature warning and protection
