PI5PD2068/2069 70m Current-Limited, Power-Distribution Switches Features Description 70m High-Side MOSFET The PI5PD2068/69 is an integrated 70m N-channel 2.1A Continuous Current MOSFET power switches for self-powered and bus- Thermal and Short-Circuit Protection powered Universal Series Bus (USB) applications. The Accurate Current Limit (2.85A typ.) devices are equipped with charge pump circuitry to drive Operating Range: 2.7V to 5.5V the internal MOSFET switch. The switchs low R , DS(on) 70m meets USB voltage drop requirements. This 0.6ms Typical Rise Time power-distribution switch is designed to set current limit Under-Voltage Lockout at 2.85A typically. Deglitched Fault Report (/OC) When the output load exceeds the current-limit threshold No /OC Glitch During Power Up or a short-circuit situation is present, the devices limit 1A Maximum Standby Supply Current the output current by switching into a constant-current Reverse Current Blocking mode, pulling the over-current (/OC) logic output low. Built-in Soft-Start When continuous heavy overloads and short-circuits PT7M2061/PT7M2065 PT7M2062(-1)/PT7M2066(-1) PT7M2065-1 UL Recognized, File Number E341484 increase the power dissipation in the switch, causing the D AND DGN PACKAGE D AND DGN PACKAGE DGN PACKAGE junction temperature to rise, a thermal protection circuit Pin Configuration (TOP VIEW) (TOP VIEW) (TOP VIEW) turns off the switch to prevent damage. Recovery from a o o o thermal shutdown is automatic once the device has GND 1 8 GND 1 8 GND 1 8 OUT /OC1 OUT cooled sufficiently. Internal circuitry ensures that the switch remains off until valid input voltage is present.
