Description
The R5117 is a power management IC featuring input voltage range from 3.5 V to 42 V. This IC includes battery voltage detector, SENSE voltage detector and 500 mA voltage regulator 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
- The battery voltage detector suitable for early warning system against battery voltage reduction
- Preventing the false detection of transient characteristic fluctuations by high-speed response voltage regulator
