... Maximum On-Resistance DESCRIPTION The SP2526 device is a dual +3.0V to +5.5V USB Supervisory Power Control Switch ideal for self-powered and bus-powered Universal Serial Bus (USB) applications. Each switch has low on-resistance (80mΩ typical) and can supply 500mA minimum. The fault currents are limited to 2 ...

... IN 4) Current Limiting Threshold: A current limiting threshold prevents damage to the de- vice and external load. 5) Thermal Shutdown: This mechanism pro- tects the SP2526 and signals a fault condition if the die temperature exceeds 135 O This function has hysteresis that pre- vents the MOSFET switches from turning on until the die temperature drops to 125 cal) ...

... USB logic controller, elimi- nating the need for the RC filter. Soft Start Condition The soft start feature of the SP2526 is imple- mented by holding the output turn-on rise time to 1ms. When off, the device has high imped- ance MOSFET channels that slowly become low impedance as the device powers on ...
