... The MAX5900/MAX5901 offer latched or autoretry fault management and are available with 200mV, 300mV, or 400mV circuit breaker thresholds. Both the MAX5900 and MAX5901 are available in small SOT23 packages, and are specified for the extended -40°C to +85°C tempera- ture range. For specific ordering information see the Selector Guide at the end of the data sheet ...

... A thermal shutdown feature protects the external MOS- FET by turning it off if the die temperature of the MAX5900/MAX5901 exceeds +125°C. The MAX5900/ MAX5901 must be in good thermal contact with the external MOSFET. See Layout Guidelines in the Applications Information section. A circuit breaker function monitors the voltage across ...

... Determining a circuit’s inrush current is necessary to | < UVLO help choose the proper MOSFET. The MAX5900/ MAX5901 regulate the inrush current by means of con- trolling the load voltage slew rate, but inrush current is also a function of load capacitance. Determine inrush current using: , and can EE ...
