MAX1922ESA+

The MAX1922ESA+ is designed as one kind of 1A current-limited switch that has several safety features to ensure that the USB port is protected. And this device is offered in a space-saving 8-pin SO package and a 10-pin TDFN package and operates over the extended (-40°C to +85°C) temperature range. And this device can be used in (1)notebook computers; (2)USB ports; (3)USB Hubs; (4)docking stations applications.

Features of the MAX1922ESA+ are:(1)Accurate Current Limit (1.4A min, 2.1A max); (2)10ms Internal OC Blanking Timeout; (3)OC Blanking During Power-Up; (4)125m (max) High-Side MOSFET; (5)Short-Circuit and Thermal Protection with Overcurrent Logic Output; (6)Undervoltage Lockout; (7)16A Quiescent Supply Current; (8)1A (max) Standby Supply Current; (9)2.7V to 5.5V Supply Range; (10)UL Recognized: UL# E211395.

The absolute maximum ratings of the can be summarized as:(1)IN, EN, OC to GND: -0.3V to +6V;(2)OUT to GND: -0.3V to (VIN + 0.3V);(3)Maximum Switch Current: 2.3A (internally limited);(4)OUT Short-Circuit to GND: Continuous;(5)Continuous Power Dissipation (TA = +70°C): 471 mW;(6)Operating Temperature Range (extended): -40°C to +85°C;(7)Storage Temperature Range: -65°C to +150°C;(8)Lead Temperature (soldering, 10s): +300°C.
