STMicroelectronics — STPMIC1 Power Management IC

STMicroelectronics has introduced the STPMIC1, a fully integrated power management IC (PMIC) for the STM32MP1 series microprocessors.

Fully programmable, the STPMIC1 provides 14 output rails to support the power requirements of application processors. The STPMIC1 can supply power to the processor as well as to external system peripherals such as SD card and Flash memories, and other system devices.

Highly efficient, this PMIC reduces power dissipation and extends battery life in portable applications, and is supported by over-current and over-voltage protection. The device’s 14 power rails include four adjustable adaptive constant on-time switching buck converters, and six LDO regulators. A 5.2 V/1.1 A boost dc-dc converter with bypass mode is suitable for a 5 V or battery input. The PMIC also features an LDO which is dedicated to DDR3 DRAM sink-source terminations in bypass mode, giving designers scope to implement low-power DRAM.

The STPMIC1 is available in five different versions: four are factory pre-programmed to meet I/O voltage requirements at 3.3 V or 1.8 V, and one is not pre-programmed. All versions can be easily customized later during the design stage, giving flexibility to engineers. An embedded non-volatile memory can store power sequencing settings and status read-outs.

The STPMIC1 is supplied in a 44-lead WFQFN package measuring 5.0 mm x 6.0 mm x 0.8 mm.
