MP62550/MP62551 Precision 60mA-1.7A Programmable Current-Limited Power Distribution Switch The Future of Analog IC Technology DESCRIPTION FEATURES MP62550/MP62551 Power Distribution Switch Up to 1.5A Continuous Output Current is designed for precision current limiting and 10% Current-Limit Accuracy provides up to 1.5A continuous output current. Adjustable Current-Limit, 60mA -1700mA (typ) It offers programmable current limit between Fast Over-current Response 2s (typ) 60mA and 1.7A (typ) with 10% accuracy by an 2.5V to 5.5V Supply Range external resistor. The switch includes an 88m 88m MOSFET (TQFN Package) N-channel Power MOSFET and operates from 1.5 A Maximum Standby Supply Current 2.5V to 5.5V input voltage. Reverse Input-Output Voltage Protection The device has built-in protection for both over Built-in Soft-Start current and increased thermal stress. For over Thermal-Shutdown Protection current, the device will limit the current by Automatic-on after Fault Removed changing to a constant current mode. It will Under-Voltage Lockout shutdown when its internal temperature Deglitched Fault Report reaches unsafe levels and recover once the FLAG won t Change State at Input UVLO device temperature reduces approx 10 C. Transition It provides built-in soft-start which controls the Bidirectional Fault Deglitch Time rise and fall times of the output voltage to limit Active Low & Active High Options the initial inrush current and voltage surges. The reverse-voltage protection feature turns off APPLICATIONS the MOSFET to protect the device. Smart Phone and PDA The FLAG output will report a fail mode (low Portable GPS Device level) when over current or over temperature is Notebook PC Set-top-box encountered. The FLAG will not change state when the input UVLO is triggered. Telecom and Network Systems PC Card Hot Swap The MP62550/MP62551 is available in space USB Power Distribution saving 6-pin TQFN 2x2mm package and All MPS parts are lead-free, halogen free, and adhere to the RoHS directive.
