The Future of Analog IC Technology MP62550/MP62551 Precision 60m A-1.7A Programmable Current-Limited Power Distribution Switch DESCRIPTION MP62550/MP62551 Power Distribution Switch is designed for precision current limiting and provides up to 1.5A continuous output current. It offers programmable current limit between 60m A and 1.7A (typ) with ±10% accuracy by an external resistor. The switch includes an 88mΩ N-channel Power MOSFET and operates from 2.5V to 5.5V input voltage. The device has built-in protection for both over current and increased thermal stress. For over current, the device will limit the current by changing to a constant current mode. It will shutdown when its internal temperature reaches unsafe levels and recover once the device temperature reduces approx 10C. It provides built-in soft-start which controls the rise and fall times of the output voltage to limit the initial inrush current and voltage surges. The reverse-voltage protection feature turns off the MOSFET to protect the device. The FLAG output will report a fail mode (low level) when over current or over temperature is ________ encountered. The FLAG will not change state when the input UVLO is triggered. The MP62550/MP62551 is available in space saving 6-pin TQFN 2x2mm package and TSOT23-6 package.
