PIN DESCRIPTIONS PIN 1: CTLA - Controls the turn-on/turn-off of channel A MOSFET with TTL as a control input. Active high for AIC1519-1 and active low for AIC1519-0. PIN 4: CTLB - Controls the turn-on/turn-off of channel B MOSFET with TTL as a control input. Active High for AIC1519-1 and active low for AIC1519-0. PIN 2: FLGA - An active-low and open-drained fault flag output for channel A. FLGA is an indicator for current limit when CTLA is active. In normal mode operation (CTLA or/and CLTB is active), it also can indicate thermal shutdown or undervoltage. PIN 5: OUTB - Channel B MOSFET switch output. PIN 6: GND - Chip power ground. PIN 7: IN - Power supply input. PIN 8: OUTA - Channel A MOSFET switch output. PIN 3: FLGB - An active-low and open-drained fault flag output for channel B. FLGB is an indicator for current limit when CTLB is active. In normal mode operation (CTLB or/and CLTA is active), it also can indicate thermal shutdown or undervoltage. 8 AIC1519

FLG output is pulled low to located signal the following fault conditions: input recommended to control supply transients. undervoltage, output current limit, and thermal Without a bypass capacitor, an output short may shutdown.

It  Transient Requirements protects the output MOSFET switches from USB supports dynamic attachment (hot plug-in) damage resulting from undesirable short circuit of peripherals. A current surge is caused by the conditions or excess inrush current, which is input capacitance of downstream device. Ferrite often encountered during hot plug-in. The low beads are recommended in series with all power limit of the current limit threshold of the AIC1519 and ground connector pins. Ferrite beads allows a minimum current of 1.4A through the reduce EMI and limit the inrush current during MOSFET switches.

A 33µF/16V tantalum or a error flag. A hysteresis of 10°C prevents the 100µF/10V electrolytic capacitor mounted close MOSFETs from turning back on until the chip to downstream connector each port should temperature drops below 125°C. However, if provide transient drop protection. thermal shutdown is triggered by chip temperature rise resulting from overcurrent fault condition of either one of the MOSFET switches, the thermal shutdown function will only turn off the switch that is in overcurrent condition and the other switch can still remain its normal capacitance current provides the needed short-term during a  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. operation. In other words, the thermal shutdown function of the two switches is independent of each other in the case of overcurrent fault. 9 AIC1519
