SPSA068-TR

Product Description

The SPSA068-TR is a power management integrated circuit (PMIC) from STMicroelectronics, designed to provide efficient voltage regulation and precise voltage references for microcontroller (MCU) applications. It integrates a synchronous buck converter and a high-accuracy voltage reference, both featuring internal power switches to minimize external component requirements. The device operates over an input voltage range of 4.2V to 19V, delivering adjustable output voltages of 5.0V, 3.3V, or 1.2V, with load currents up to 1A. A low-power mode reduces quiescent current to approximately 50 µA, enhancing efficiency under light-load conditions. The SPSA068-TR includes an SPI interface for diagnostics, programming, monitoring, and an external window watchdog, supporting functional safety requirements as defined by automotive safety integrity levels. It is housed in a 32-lead QFN package, facilitating compact and reliable integration into various electronic systems.
