The MAX5963 dual hot-swap and diode ORing controller provides complete protection for dual-supply high availability systems. The device operates from 7.5V to 76V and provides hot-swap and low voltage-drop diode ORing functionality for two 7.5V to 76V outputs.
The MAX5963 allows for the safe insertion and removal of system line cards and FireWire® peripherals into a live backplane by providing inrush current control and active current limiting. The device controls external n-channel power MOSFETs to perform low-voltage-drop ORing, inrush current control, and current limiting functions. The current-limit function actively limits the current drawn by the load, protecting the load from a short-circuit condition. The MAX5963 also features a circuit-breaker function that disconnects the power to the load if the load current exceeds the circuit-breaker limit for a programmable circuit-breaker timeout.
The MAX5963 features an autoretry/latchoff input. In autoretry mode, the MAX5963 automatically restarts the turned-off channel after a programmable delay. In latchoff mode, the MAX5963 latches the channel off.
The MAX5963 consumes less than 10µA from the PWR supply in system power-off mode.
The MAX5963 is available in a 40-pin TQFN package (6mm x 6mm) and operates over the 0°C to +85°C upper commercial temperature range.
