However higher capacitance could help reduce the voltage drop. Further more, bypassing the output with a 10μF ceramic capacitor improves the immunity of the device to short-circuit transients, because an output short will cause ringing on the input without the input capacitor. It could destroy the internal circuitry when the input transient voltage exceeds the absolute maximum supply voltage even for a short duration. Under Voltage Lockout A voltage sense circuit monitors the input voltage. When the input voltage is below approximately 2.4V, a control signal turns off the power switch. Enable The logic enable controls the power switch, the bias for the charge pump, driver, and other circuitry to reduce the supply current. The EN control pin must be driven to a logic high or logic low for a clearly defined signal input. Floating these control lines may cause unpredictable operation. Over-Current Protection The DIO7003 responds to over current conditions by limiting output current to the ILIM levels. When an over current condition is detected, the device maintains a constant output current and reduces the output voltage accordingly. Complete shut down occurs only if the fault is present long enough to activate thermal limit. Two possible overload conditions can occur. In the first condition, an excessive load occurs while the device is enabled. When the excessive load occurs, very high currents may flow for a short time before the current limit circuit can react. After the current limit circuit has tripped (reached the overcurrent trip threshold) the device switches into constant current mode to limit the current close to ILIM. In the second condition, the load is gradually increasing beyond the recommended operating current. The current is permitted to rise until the currentlimit threshold (ILIM) is reached or until the thermal limit of the device is www.dioo.com © 2016 DIOO MICROCIRCUITS CO., LTD DIO7003• Rev 1.3 5.5V Low Loss Power Distribution Switch Block Diagram DIO7003 Thermal Protection Thermal protection prevents damage to the IC when heavy overload or short circuit conditions are present for extended periods of time. The conditions force the DIO7003 into constant current mode, and under short circuit conditions, the voltage across the switch is equal tothe input voltage. The increased dissipation causes the junction temperature to rise to high levels. The protection circuit senses the junction temperature of the switch and shuts it off. Hysteresis is built into the thermal sense circuit, and after the device has cooled approximately 20 degrees, the switch turns back on. The switch continuesto cycle in this way until the overload or input power is removed. Reverse-voltage Protection The reverse-voltage protection feature turns off the P-channel MOSFET whenever the output voltage exceeds the input voltage by 175mV (typ) for 4ms (typ). A reverse current of (VOUT-VIN)/RDS(on) will be present when this occurs. This prevents damage to devices on the input side of the DIO7003 by preventing significant current from sinking into the input capacitance. The DIO7003 devices allow the P-channel MOSFET to turn on once the output voltage goes bellow the input voltage for the same 4ms deglitch time. FLG Output An error Flag is an open-drained output of an N-channel MOSFET. Flag output is pulled low when the below conditions happen: input under voltage lockout, output current limit, output short circuit and over temperature shut down. The flag response delay time is 5ms typically. www.dioo.com © 2016 DIOO MICROCIRCUITS CO., LTD DIO7003• Rev 1.3 5.5V Low Loss Power Distribution Switch exceeded. The DIO7003 is capable of delivering current up to the current limit threshold (ILIM) without damaging the device. Once the threshold has been reached, the device switches into its constant current mode. DIO7003 TA=25°C VIN = 5V, unless otherwise noted.
