Applications

„ 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 General Description The G524 is an integrated power switch for self-powered and bus-powered Universal Serial Bus (USB) applications. G524A, G524B, G524C, G524D are 70m Ω R DS(ON) . Several Protection features include current limiting and thermal shutdown to prevent catastrophic switch fail- ure caused by increasing power dissipation when con- tinuous heavy loads or short circuit occurs. 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. When the output voltage is higher than input voltage, the power switch is turned off by internal output reverse-voltage comparator. OC is an open-drain output report over-current or over-temperature event and has typical 9ms deglitch timeout period. In addition, OC (G524X3/4, X=A, B, C, D) also reports output reverse-voltage condition with typical 5ms deglitch timeout period. Pin Configuration Typical Application Circuit 0.1µF 22µF Load OC EN(EN) 1µF Power Supply 2.7V to 5.5V OUTIN ON OFF *: 1µF of input capacitor is enough in most application cases. If the PCB trace of power rail to IN is long, larger input capacitor is necessary.

OUT (output) is the source of the output MOSFET. In a typ- ical application, current flows through the switch from IN to OUT toward the load. Both OUT pins must be connected together to the load. Thermal Shutdown Thermal shutdown protects G524 from excessive power dissipation. If the die temperature exceeds 140°C, the MOSFETS switch is shut off. 20 °C of hystersis prevents the switch from turning on until the die temperature drops to 120 °C. Thermal shutdown circuit functions only when the switch is enabled. Undervoltage Lockout UVLO (undervoltage lockout) prevents the output MOSFET from turning on until IN (input voltage) ex- ceeds 2.4V typically. After the switch turns on, if the voltage drops below 2.4V typically, UVLO shuts off the output MOSFET. Over Current Trigger Point The typical over current trigger point of G524 is 2.5A, 2.1A, 2A, 1.5A. There is foldback of current limit when V IN>3.5V and V OUT<1V. (See Typical Performance Characteristics) Output Reverse-Voltage Protection The output reverse-voltage protection turns off the MOSFET switch whenever the output voltage is higher than the input voltage by 20mV (typ) for 5ms (typ) and the MOSFET switch will turn on when output re- verse-voltage condition is removed for 5ms (typ). OC Function The OC open-drain output is asserted (active low) when an over current condition is encountered after a 9-ms deglitch timeout. The output remains asserted until the overcurrent condition is removed. Over tem- perature condition is also reported immediately by OC open-drain output. In addition, OC (G524X3/4, X=A, B, C, D) is also asserted (active low) in output reverse-voltage condition with typical 5ms deglitch timeout period until the output reverse-voltage condi- tion is removed. Applications Information Supply Filtering A 1 µF bypass capacitor from IN to GND, located near the G524, is strongly recommended to control supply transients. Without a bypass capacitor, an output short may cause sufficient ringing on the input (from supply lead inductance) to damage internal control circuitry. Input transients must not exceed the absolute maxi- mum supply voltage (V IN max = 6V) even for a short duration. EN, the Enable Input EN must be driven logic high or logic low for a clearly defined input. Floating the input may cause unpre- dictable operation. EN should not be allowed to go negative with respect to GND.
