PMICs

Our portfolio provides multi-channel power management ICs (PMICs) with special features developed for the power requirements of various applications, including LCD-TV, Car Infotainment, and set-top box (STB).

Level Shift

Voltage level translators, or logic level shifts, solves incompatibility differences between different power domains. Our bidirectional voltage level translators implement automatic direction sensing for two-way level translation applications.

Load Switches

Load switches are a simple, easy-to-use and cost-effective way to turn on and off power supply rails. Our portfolio includes various current, voltage, channel, package, and timing options for a diverse range of applications, such as LV, HV, Fast Response, and SD Card. These devices have a slew-rate controlled turn-on characteristic (soft start) to eliminate inrush current and the resulting excessive voltage droop.

USB Type-C Solutions

Our USB Type-C portfolio offers the flexibility and integration required to design and implement products compatible with the latest standards for a diverse range of applications, including Type-C DFP controllers, VBUS power switches, port protectors, HV LDO for dead battery, and power MUX.

USB Type-A Solutions

Our USB Type-A portfolio offers the flexibility and integration required to design and implement products compatible with the latest standards for a diverse range of applications, including USB Charging Controller and VBUS power switch.

eFuse

Conventional fuses (glass tube fuses and chip fuses) protect circuits by fusing the built-in alloy parts due to Joule heat when the current exceeds the rated value. However, these physical fuses have disadvantages such as slow fusing time, indefinite breaking current, and the need for replacement work due to destruction by a single over-current event.
Unlike conventional fuses, the eFuse (electronic fuse) has a fast current blocking function because the MOSFET is quickly turned off when excessive current flows. In addition, it is not destroyed by a single over-current event and can be used repeatedly. Besides, it can merge various protection functions such as over-voltage protection, over-temperature protection, and short-circuit protection. Therefore, this product can reduce maintenance costs and recovery time for repairs.
Another advantage is that eFuse realizes much simpler circuit designs with fewer components and a smaller area than discrete parts.

Switching Regulators

Switching regulators can be used under wide input and wide output voltage range,
and provide accurate voltage output to loads with extremely high efficiency for a wide range of applications, including battery-powered mobile applications, automotive applications, and computing applications. To select the correct type of switching regulator, you need to consider the application input and output voltage and load current conditions.

Linear Regulators

Low dropout linear regulators(LDOs) can be used in relatively low-power applications to convert a higher input voltage to a lower output voltage for use by the load.
FA has developed a series of LDOs for a wide range of applications, including battery-powered mobile applications, automotive applications, and computing applications. To select the correct linear regulator, you need to consider the application input and output voltage and load current conditions.
