R5116 Series
42V Input Voltage Regulator with Window Voltage Detector
-
Description
The R5116 is a power management IC featuring input voltage range from 3.5 V to 42 V. This IC includes 500 mA voltage regulator and window voltage detector in a single chip.
This IC can be used under high temperature environment. It offers the maximum operating temperature of 105°C for consumer applications, and 125°C for industrial and automotive applications. This product for industrial applications is characterized to −50°C, and operates in a wide temperature range from low temperature to high temperature.
Key Benefits
- Reducing components and improving functional safety
- High accuracy of the output voltage and the detector threshold: -1.25% to 0.75%
- Preventing the false detection of transient characteristic fluctuations by high-speed response voltage regulator
