Flag output is pulled low to signal the following fault conditions: input undervoltage, output current limit, and thermal shutdown. The current limit flag response delay time is 9ms.  Current Limit The current limit threshold is preset internally. It protects the output MOSFET switches from damage resulting from undesirable short circuit conditions or excess inrush current, which is often encountered during hot plug-in. The error flag signals when any current limit conditions occur.  Thermal Shutdown When temperature of AIC6163 exceeds 145C for any reasons, the thermal shutdown function turns MOSFET switch off and signals the error flag. A hysteresis of 20C prevents the MOSFETs from turning back on until the chip temperature drops below 125C.  Enable Control lead inductance) to damage internal control circuitry.  Transient Requirements USB supports dynamic attachment (hot plug-in) of peripherals. A current surge is caused by the input capacitance of downstream device. Ferrite beads are recommended in series with all power and ground connector pins. Ferrite beads reduce EMI and limit the inrush current during hot-attachment by filtering high-frequency signals.  Short Circuit Transient Bulk capacitance provides the short-term transient current needed during a hot-attachment event. A 22F/10V ceramic capacitor mounted close to downstream connector each port should provide transient drop protection.  Printed Circuit Layout The power circuitry of USB printed circuit boards requires a customized layout to maximize thermal dissipation and to minimize voltage drop and EMI. Enable must be driven logic high or logic low for a clearly defined input. Floating the input may cause unpredictable operation.  Under-voltage Lockout UVLO (undervoltage lockout) prevents the output MOSFET from turning on until input voltage exceeds 2.5V typically. After the switch turns on, if the input voltage drops below 2.3V typically, UVLO shuts off the output MOSFET.  Supply Filtering A 1F bypass capacitor from USB IN to GND, located near the device, is strongly recommended to control supply transients. Without a bypass capacitor, an output short may cause sufficient ringing on the input (from supply 8 AIC6163  PHYSICAL DIMENSIONS (unit: mm)  SOT-23-5 A A E E1 D e e1 SEE VIEW B WITH PLATING c A A2 b SECTION A-A 0.25 A1 BASE METAL GAUGE PLANE SEATING PLANE L1 θ L VIEW B Note : 1.
