LTC4236, a dual ideal diode-OR and single Hot Swap controller, features a load current monitoring output. High availability systems—servers, network routers, and solid-state drives—power circuit boards with multiple power supply feeds. The LTC4236 combines (diode-ORs) two power supplies while providing inrush current control, over current protection, and current monitoring, all in a compact footprint.
Summary of features:
- Ideal diode-OR & inrush current control for redundant supplies
- Load current monitoring output
- Low loss replacement for power Schottky diode-OR
- Enables safe board insertion into a live backplane
- 2.9 to 18-v operating range
- Fault, power good & diode status outputs
- 28-pin 4 x 5-mm QFN package
