Description
The RS31320 device integrates two independent electronics fuses, one for 5V rail and the other for 12V. With the low Ron resistance, the 5V rail supports 2.5A continuous current, while the 12V rail supports 3.5A continuous current.
To regulate the input inrush current during startup, the output voltage rising slew rate of each rail can be configured individually.
The device also has fixed over-current protection, input UV and OV protection, and over-temperature protection.
The device is available in TSOT23-8L, 2.8×2.9 mm package.
Applications
- HDD and SSD drivers
- Multiple battery management
- Redundant and standby power system
- Power path management
- Surveillance system
