Placing a high-value electrolytic capacitor on the input (10-μF minimum) 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 0.01-μF to 0.1-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 current-sense resistors, sense FETs do not increase the series resistance of the current path. When an overcurrent condition is detected, the device maintains a constant output current and reduces the output voltage accordingly. Complete shutdown occurs only if the fault stays long enough to activate thermal limiting. 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 AP2181A/AP2191A senses the short circuit and immediately clamps output current to a certain safe level namely I LIMIT. 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 I LIMIT. 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 AP2181A/AP2191A 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 is set at ILIMIT. Note that when the output has been shorted to GND at extremely low temperature (< -30°C), a minimum 120-μF electrolytic capacitor on the output pin is recommended. A correct capacitor type with capacitor voltage rating and temperature characteristics must be properly chosen so that capacitance value does not drop too low at the extremely low temperature operation. A recommended capacitor should have temperature characteristics of less than 10% variation of capacitance change when operated at extremely low temp. Our recommended aluminum electrolytic capacitor type is Panasonic FC series. 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. The FLG output remains low until both over-current and over-temperature conditions are 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 AP2181A/AP2191A 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-circuit faults are present for extended periods of time. The AP2181A/AP2191A 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 or short-circuit 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 or over-current occurs with 7-ms deglitch. AP2181A/ AP2191A Document number: DS37618 Rev. 1 - 2 9 of 17 www.diodes.com March 2015 © Diodes Incorporated AP2181A/ AP2191A Application Information (cont.) Undervoltage Lockout (UVLO) Undervoltage Lockout (UVLO) function keeps the internal power switch from being turned on until the power supply has reached at least 1.9V, even if the switch is enabled. Whenever the input voltage falls below approximately 1.9V, 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. Host/Self-Powered HUBs Hosts and Self-Powered HUBs (SPH) have a local power supply that powers the embedded functions and the downstream ports (see Figure 2). This power supply must provide from 5.25V to 4.75V to the board side of the downstream connection under both full-load and no-load conditions. Hosts and SPHs are required to have current-limit protection and must report over-current conditions to the USB controller. Typical SPHs are desktop PCs, monitors, printers, and stand-alone hubs. Downstream USB Ports Power Supply 3.3V 5V D+ D- AP2181A 2,3 IN OUT 0.1uF VBUS 0.1uF 5 4 USB Control 6,7 FLG EN 120uF GND GND 1 Figure 2 Typical One-Port USB Host / Self-Powered Hub Generic Hot-Plug Applications In many applications it may be necessary to remove modules or PC boards while the main unit is still operating. These are considered hot-plug applications. Such implementations require the control of current surges seen by the main power supply and the card being inserted. The most effective way to control these surges is to limit and slowly ramp the current and voltage being applied to the card, similar to the way in which a power supply normally turns on. Due to the controlled rise and fall times of the AP2181A/AP2191A, these devices can be used to provide a softer start-up to devices being hot-plugged into a powered system. The UVLO feature of the AP2181A/AP2191A also ensures that the switch is off after the card has been removed, and that the switch is off during the next insertion. By placing the AP2181A/AP2191A between the VCC input and the rest of the circuitry, the input power reaches these devices first after insertion. The typical rise time of the switch is approximately 1ms, providing a slow voltage ramp at the output of the device. This implementation controls system surge current and provides a hot-plugging mechanism for any device. Dual-Purpose Port Applications AP2181A/AP2191A is suitable for use in dual-purpose port applications in which a single port is used for data communication between the host and peripheral devices while simultaneously maintaining a charge to the battery of the peripheral device. An example of this is a shared HDMI/MHL (Mobile High-Definition Link) port that allows streaming video between an HDTV or set-top box and a smartphone or tablet while maintaining a charge to the smartphone or tablet battery. In such dual-purpose port applications, it is important to insure Vin of the AP2181A/AP2191A is ramped to its operating voltage prior to enabling the output.
