PMIC Manufacturers | Power Management IC Manufacturers

This page mentions PMIC Manufacturers i.e. Power Management IC Manufacturers or vendors. The popular manufacturers of PMIC are Analog devices, Maxim, STMicroelectronics, TI, NXP, RENESAS, Microchip etc.

What is PMIC ?

The IC (Integrated Circuit) used for various power management tasks is called PMIC. It reduces space requirement to greater extent in battery powered devices such as mobile phones, IoT end devices such as smart watches and other smart devices. These ICs are solid state devices which control flow of electrical power.

Following are the typical functions of a PMIC.
• It performs DC to DC conversion.
• It can charge the battery on board.
• It can help in power source or power path selection.
• It does voltage scaling.
• It is used for power sequencing on the board.
• It can be used for voltage supervision i.e. for overvoltage and undervoltage protection.
