AP2401/AP2411 2.0A SINGLE CHANNEL CURRENT-LIMITED POWER SWITCH WITH LATCH-OFF Description Pin Assignments NEW PRODUCT The AP2401 and AP2411 are single channel current-limited integrated high-side power switches optimized for Universal Serial Bus (USB) and other hot-swap applications. The family of devices complies with USB standards and is available with both polarities of Enable input. (Top View) The devices have fast short-circuit response time for improved overall system robustness, and have integrated output discharge function to ensure completely controlled discharging of the output voltage capacitor. They provide a complete protection solution for applications subject to heavy capacitive loads and the prospect of short circuit, and offer reverse current blocking, over-current, over-temperature and short-circuit protection, as well as controlled rise time and under-voltage lockout functionality. A 7ms deglitch capability on the open-drain Flag output prevents false over-current reporting and does not require any external components. AP2401 and AP2411 will be latched off after 7ms deglitch. All devices are available DFN3030-8 packages. in SO-8, MSOP-8EP GND 1 8 NC IN 2 7 OUT IN 3 6 OUT EN 4 5 FLG SO-8 (Top View) GND 1 8 NC IN 2 7 OUT IN 3 6 OUT EN 4 5 FLG and MSOP-8EP (Top View) Features • Single channel current-limited power switch • Output discharge function • Output current latch-off when OCP triggered • Fast short-circuit response time: 2µs • 2.5A accurate current limiting • Reverse current blocking • 70mΩ on-resistance • Input voltage range: 2.7V – 5.5V • Built-in soft-start with 0.6ms typical rise time • Over-current and thermal protection • Fault report (FLG) with blanking time (7ms typ) • ESD protection: 4KV HBM, 300V MM • Active low (AP2401) or active high (AP2411) enable • Ambient temperature range: -40ºC to 85°C • SO-8, MSOP-8EP and DFN3030-8: Available in “Green” GND 1 8 NC IN 2 7 OUT IN 3 6 OUT EN 4 5 FLG DFN3030-8 Applications • LCD TVs & Monitors • Set-Top-Boxes, Residential Gateways • Laptops, Desktops, Servers, e-Readers • Printers, Docking Stations, HUBs Molding Compound (No Br, Sb) • Lead Free Finish / RoHS Compliant (Note 1) • UL Recognized, File Number E322375 (Pending) • IEC60950-1 CB Scheme Certified Note: 1.

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 0.1μF to 1.0μF ceramic capacitor improves the immunity of the device to short circuit transients. 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: Over-current and Short Circuit Protection An internal sensing FET is employed to check for overcurrent conditions. Unlike current-sense resistors, sense FETs do not increase the series resistance of the current path. When an overcurrent condition is detected, the devices will limit the current until the overload condition is removed or the internal deglitch 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 ILIMIT, 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 current 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 the current is clamped at ILIMIT 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 (ITRIG) is reached or until the thermal limit of the device is exceeded. The AP2401/AP2411 is capable of delivering current up to the current-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 ILIMIT 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. AP2401/AP2411 Document number: DS35113 Rev. 3 - 2 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-circuit 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 thermal sense circuitry turns the power switch off, thus preventing the power switch from damage. Hysteresis is built into 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, even if the switch is enabled. Whenever the input voltage falls below approximately 2V, the power switch is quickly turned 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. 10 of 15 www.diodes.com June 2011 © Diodes Incorporated AP2401/AP2411 2.0A SINGLE CHANNEL CURRENT-LIMITED POWER SWITCH WITH LATCH-OFF Application Notes Discharge Function the external storage capacitor.
