STMicroelectronics Announces Power Management ICs Optimized for STM32 Microprocessors in Industrial Equipment

STMicroelectronics (NYSE: STM), a global semiconductor leader serving customers across the spectrum of electronics applications, today announced the STPMIC1L and STPMIC2L, Power Management ICs (PMICs) that leverage ST's embedded processors based on Arm® Cortex®-A microprocessor cores for performance-driven industrial equipment. Optimized for the 32-bit STM32MP1x and 64-bit STM32MP2x series, these PMICs enable low-cost power and protection, along with board-area reduction, hardware design simplification, and minimized component costs. They include multiple LDOs and DC-DC buck converters for the MPU's various power rails, as well as LDOs optimized for powering external DDR DRAM. Both devices are ideal for POS terminals, network gateways, home automation systems, edge-processing platforms, printers, barcode scanners, and smart meter systems. With an extended temperature rating from -40°C to 125°C, they also suit harsh environments found in industrial controls, thermostats, and smart factory equipment. The STPMIC1L for STM32MP1 series features two DC-DC buck converters, four LDOs, one LDO for DRAM, and two external pins for power control. The STPMIC2L for STM32MP1 series offers three DC-DC buck converters, seven general-purpose LDOs, one LDO for DRAM, and three external pins for power control. Both accept a wide input voltage range of 2.8V to 5.5V, simplifying the design of equipment powered by low-voltage AC-DC power adapters, USB ports, or lithium-ion or lithium-polymer batteries. To ensure fast transient response and optimize efficiency, the buck converters in these PMICs use an adaptive Constant On-Time (OCT) scheme that dynamically adjusts voltage. Safety and protection features include programmable output-discharge modes, selectable overcurrent protection (OCP), and power-rail monitoring. They also handle power-up/power-down sequencing to meet MPU precision and settling-time specifications. Two evaluation boards, STEVAL-PMIC1LKV1 and STEVAL-PMIC2LKV1, are available to accelerate project starts and shorten development cycles. Featuring a dedicated GUI (Graphical User Interface), they simplify PMIC configuration, monitoring, and NVM parameter setting on the evaluation boards. Both are comprehensively supported by OpenSTLinux, part of the STM32 MPU ecosystem. Both devices are in volume production. The STPMIC1L is available in a 28-pin VFQFPN package (4x4mm) for about $1.34 per unit in 1,000-unit quantities. The STPMIC2L is available in a VFQFPN40 package (5x5mm) for about $1.77 per unit in 1,000-unit quantities. For more information, visit the website.
