APPLICATION INFORMATION Error Flag An error Flag is an open-drained output of an N-channel MOSFET. FLG output is pulled low to signal the following fault conditions: input undervoltage, output current limit, and thermal shutdown. the thermal shutdown function will only turn off the switch that is in overcurrent condition and the other switch can still remain its normal operation. In other words, the thermal shutdown function of the two switches is independent of each other in the case of overcurrent fault. 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 low limit of the current limit threshold of the AIC1529 allows a minimum current of 1A through the MOSFET switches. The error flag signals when any current A 0.1µF to 1µF bypass capacitor from 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 lead inductance) to damage internal control circuitry. USB supports dynamic attachment (hot plug-in) Thermal Shutdown When temperature of AIC1529 exceeds 135°C for any reasons, the thermal shutdown function turns both MOSFET switches off and signals the error flag. A hysteresis of 10°C prevents the MOSFETs from turning back on until the chip temperature drops below 125°C. However, if shutdown Supply Filtering Transient Requirements limit conditions occur. thermal condition of either one of the MOSFET switches, is triggered by chip 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 hot-attachment the by inrush filtering current during high-frequency signals. temperature rise resulting from overcurrent fault 8 AIC1529 Short Circuit Transient Bulk capacitance Printed Circuit Layout short-term The power circuitry of USB printed circuit boards transient current needed during a hot-attachment requires a customized layout to maximize thermal event.
