STMicroelectronics (NYSE: STM, hereinafter ST) has announced the "STPMIC1L" and "STPMIC2L" power management ICs (PMICs), which enable the use of ST's embedded processors based on Arm® Cortex®-A microprocessor (MPU) cores in performance-critical industrial equipment.
Optimized for the 32-bit STM32MP1x series and the 64-bit STM32MP2x series respectively, these PMICs provide low-cost power supply and protection functions, while contributing to reduced board space, simplified hardware design, and minimized component costs. In addition to multiple fixed and variable output LDOs and DC-DC buck converters corresponding to each MPU power rail, each PMIC also features an LDO optimized for powering external DDR DRAM.
Both products are ideal for POS terminals, network gateways, home automation systems, edge processing platforms, printers, barcode scanners, and smart meter systems. Furthermore, with an extended temperature rating from -40°C to 125°C, they are suitable for harsh environments such as industrial control equipment, thermostats, and smart factory equipment.
The STPMIC1L for the STM32MP1 series features two DC-DC buck converters, four LDOs, one LDO for DRAM, and two external pins for power control. The STPMIC2L for the STM32MP1 series features three DC-DC buck converters, seven general-purpose LDOs, one LDO for DRAM, and three external pins for power control. Both support 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, lithium-ion batteries, or lithium-polymer batteries.
To ensure fast transient response and optimize efficiency, the buck converters of these PMICs employ an adaptive constant on-time (OCT) method, allowing dynamic voltage adjustment. Safety and protection features include programmable output discharge modes, selectable overcurrent protection (OCP) functions, and power rail monitoring. They also handle power-up/power-down sequence control and meet MPU accuracy and settling time specifications.
Two types of evaluation boards that contribute to quick project start-up and reduced development time.
