2.0A SINGLE CHANNEL CURRENT-LIMITED POWER SWITCH WITH LATCH-OFF AP2401/AP2411 Document number: DS35113 Rev. 3 - 2 10 of 15 www.diodes.com June 2011 © Diodes Incorporated NEW PRODUCT Application Notes Power Supply Considerations A 0.1μF to 2.2 μF X7R or X5R ceramic bypass capacitor placed between IN and GND, close to the device, is recommended. When an external power supply is used, or an additional ferrite bead is added to the input, high inrush current may cause voltage spikes higher than the device maximum input rating during short circuit condition. In this case a 2.2μF or bigger capacitor is recommended. Placing a high-value electrolytic capacitor on the input and output pin(s) is recommended when the output load is heavy. This precaution reduces power-supply transients that may cause ringing on the input. Additionally, bypassing the output with a 0.1μ F to 1.0 μF ceramic capacitor improves the immunity of the device to short circuit transients. Over-current and Short Circuit Protection An internal sensing FET is employed to check for over- current conditions. Unlike cu rrent-sense resistors, sense FETs do not increase the series resistance of the current path. When an overcurrent c ondition is detected, the devices will limit the current until the overload condition is removed or the internal deglit ch time (7-ms typical) is reached and the device is turned off. The device will remain latched off even overload condition is removed until power is cycled or the device enable is toggled. Three possible overload conditions can occur. In the first condition, the output has been shorted to GND before the device is enabled or before VIN has been applied. The AP2401/AP2411 senses the short circuit and immediately clamps output current to a certain safe level namely I LIMIT, and turns off after deglitch time(7-ms typical). In the second condition, an output short or an overload occurs while the device is enabled. At the instance the overload occurs, higher current may flow for a very short period of time before the curr ent limit function can react. After the current limit function has tripped (reached the over-current trip threshold), the device switches into current limiting mode and th e current is clamped at I LIMIT current for deglitch time period (7-ms typical), and then turned off. In the third condition, the load has been gradually increased beyond the recommended operating current. The current is permitted to rise until the current-limit threshold (I TRIG) is reached or until the thermal limit of the device is exceeded. The AP2401/AP2411 is capable of delivering current up to the cu rrent-limit threshold without damaging the device. Once the threshold has been reached, the device switches into its current limiting mode and output current is clamped at I LIMIT for deglitch time period (7-ms typical), and then turned off. FLG Response When an over-current or over-temperature shutdown condition is encountered, the FLG open-drain output goes active low after a nominal 7-ms deglitch timeout. When that happens, the FLG will remain low and the switch will be latched off until the fault condition is removed. Connecting a heavy capacitive load to the output of the device can cause a momentary over-current condition, which does not trigger the FLG due to the 7-ms deglitch timeout. The AP2401/AP2411 is designed to eliminate false over-current reporting without the need of external components to remove unwanted pulses. Power Dissipation and Junction Temperature The low on-resistance of the internal MOSFET allows the small surface-mount packages to pass large current. Using the maximum operating ambient temperature (TA) and RDS(ON), the power dissipation can be calculated by: PD = RDS(ON)× I2 Finally, calculate the junction temperature: TJ = PD x RθJA + TA Where: TA= Ambient temperature°C RθJA = Thermal resistance PD = Total power dissipation Thermal Protection Thermal protection prevents the IC from damage when heavy-overload or short-circ uit faults are present for extended periods of time. The AP2401/AP2411 implements a thermal sensing to monitor the operating junction temperature of the power distribution switch. Once the die temperature rises to approximately 140°C due to excessive power dissipation in an over-current condition, the internal ther mal sense circuitry turns the power switch off, thus preventing the power switch from damage. Hysteresis is built in to the thermal sense circuit allowing the device to cool down approximately 25°C before the switch turns back on. The switch continues to cycle in this manner until the load fault or input power is removed. The FLG open-drain output is asserted when an over-temperature shutdown occurs with 7-ms deglitch. When the FLG is asserted, the switch will be latched off until the temperature drops to 20 °C below the thermal shutdown threshold and the power or EN pin is cycled. Under-voltage Lockout (UVLO) Under-voltage lockout function (UVLO) keeps the internal power switch from being turned on until the power supply has reached at least 2V, ev en if the switch is enabled. Whenever the input voltage falls below approximately 2V, the power switch is quickly tu rned off. This facilitates the design of hot-insertion systems where it is not possible to turn off the power switch before input power is removed.
