Description
The TPS241x controller, in conjunction with an external N-channel MOSFET, emulates the function of a low forward-voltage diode.
The device can be used to combine multiple power supplies to a common bus in an N+1 configuration, or to combine redundant input power buses.
Features
- 1 Control external FET for N+1 and ORing.
- Wide supply voltage range of 3 V to 16.5 V.
- Controls buses from 0.8 V to 16.5 V.
- Linear or on/off control method.
- Internal charge pump for N-channel MOSFET.
- Rapid device turnoff protects bus integrity.
- Positive gate control on hot insertion.
- Soft turn on reduces bus transients.
- Input voltage monitoring.
- Shorted gate monitor.
- MOSFET control-state indicator.
