US107 Datasheet | Unisonic Technologies

DESCRIPTION The UTC US107 is a power distribution switch. It is intended for applications such as USB where heavy capacitive loads and short-circuits are likely to be encountered. This family offers multiple devices with fixed current-limit thresholds for applications between 1.2 A, 1.7A and 2.5 A. The RDS(ON) of the MOSFET switch is as low as 70mΩ. OC is open-drain output report over-current or over-temperature event which has typical 9ms deglitch timeout period, also reports output reverse-voltage condition with typical 5ms deglitch timeout period. The UTC US107 incorporates protection circuits including current limiting circuit with foldback function, thermal shutdown circuit designed to prevent catastrophic switch failure due to increasing power dissipation when continuous heavy loads or short circuit occurs. Besides, a built-in charge pump is used to drive the N-channel MOSFET that is free of parasitic body diode to eliminate any reversed current flow across the switch when it is powered off. The UTC US107 is applied in high-side power protection switch, USB power management, USB host and self-powered bubs, USB bus-powered hubs, hot plug-in power supplies, battery-charger circuits. - FEATURES 4 5 SOT-25 - Single power switch family - Operating range: 3.0V~5.5V - 130µA quiescent supply current - 1µA maximum shutdown supply current - 70mΩ high-side MOSFET - 1m S typical rise time - Under voltage lockout - Logic level enable pin, available with Active-high or active-low version - No reverse current when power off - Output shutdown pull-low resister - Deglitched open-drain over-current flag output ( OC ) - Output reverse-voltage protection - ORDERING INFORMATION Ordering Number Lead Free Halogen Free US107xx L-AF5-R US107xx G-AF5-R Note: Pin Assignment: O: OUT G: GND OC: OC Package SOT-25 Pin Assignment 12345 O G OC C I C: CE/ CE I: IN Packing Tape Reel US107xx G-AF5-R (1)Packing Type (2)Package Type (3)Green Package (4)Active (5)ILIMIT (1) R:...
