AIC1529 Quad USB High-Side Power Switch FEATURES • 110mΩ (5V Input) High-Side MOSFET Switch. 500mA Continuous Load Current per Channel. 220µA Typical On-State Supply Current. 1µA Typical Off-State Supply Current. Current-Limit / Short Circuit Protection. Thermal Shutdown Protection under Overcurrent Condition. Undervoltage Lockout Ensures that Switch is off at Start Up. Output can be Forced Higher than Input (Off-State). Open-Drain Fault Flag. Slow Turn ON and Fast Turn OFF. Enable Active-High or Active-Low. Guaranteed minimum output rise time limits inrush current during hot plug-in as well as DESCRIPTION The AIC1529 is a quad high-side power switch for self-powered and bus-powered Universal Serial Bus (USB) applications. Both high-side switches are MOSFET with 110mΩ RDS(ON), which meets USB voltage drop requirements for maximum transmission wire length. Multi-purpose open-drain fault flag output indicates over-current limiting, thermal shutdown, or undervoltage lockout for each channel. Output current is typically limited to 1.3A, and the thermal shutdown functions of the power switches independently control their channel under overcurrent condition. APPLICATIONS • USB Power Management. Hot Plug-In Power Supplies. Battery-Charger Circuit. minimizing EMI and prevents the voltage at upstream port from dropping excessively.

CTLA (B,C,D)- Controls the turn-on/turn-off of channel A (B,C,D) MOSFET with TTL as a control input. Active high for AIC1529-1 and active low for AIC1529-0. FLGA (B,C,D)- An active-low and open-drained fault flag output for channel A (B,C,D). FLGA (B,C,D) is an indicator for current limit when CTLA (B,C,D) is active. In normal mode operation (CTLA(C) or/and CLTB(D) is active), it also can indicate thermal undervoltage. shutdown or 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. 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 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 limit conditions occur. Supply Filtering 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. 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 by inrush filtering current during hot-attachment signals. high-frequency Thermal Shutdown W hen 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 thermal shutdown is triggered by chip temperature rise resulting from overcurrent fault 8 AIC1529 Short Circuit Transient Bulk capacitance provides the short-term transient current needed during a hot-attachment event. A 33µF/16V tantalum or a 100µF/10V electrolytic 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. 9 PHYSICAL DIMENSIONS (unit: mm) SOP-16 AIC1529 10 °8 7 2. 1 0 5. 0 0 2. 6 C S B 7 2. 1 0 0. 4 0 0. 0 1 5 2. 0 1 5. 0 5 2. 0 5 7. 1 .
