When the IC is disabled, the supply ting off until internal circuitry is operating properly. The UVLO circuit has hysteresis and a de-glitch feature so current is reduced to less than 1µA. The enable input is compatible with both TTL and CMOS logic levels. The that it will typically ignore undershoot transients on the input. When input voltage exceeds the UVLO threshold, EN/ENB pins cannot be left floating. the output voltage starts a soft-start to reduce the inrush current.

The internal power MOSFET does not have the tion temperature cools by 20 oC, the internal thermal sense circuit will enable the device, resulting in a pulsed body diode. When IC is off, the MOSFET prevents a current flowing from the VOUT back to VIN and VIN to VOUT. output during continuous thermal protection. Thermal protection is designed to protect the IC in the event of Current-Limit Protection over temperature conditions. For normal operation, the junction temperature cannot exceed TJ=+125oC. The APL3516A/B/C/D series of power switches provide the current-limit protection function. During current-limit, the devices limit output current at current limit threshold. For reliable operation, the device should not be operated in current limit for extended period. Short-Circuit Protection When the output voltage drops below 1.5V, which is caused by the over load or short circuit, the devices limit the output current down to a safe level. The short circuit current limit is used to reduce the power dissipation during short circuit condition. If the junction temperature is over the thermal shutdown temperature, the device will enter the thermal shutdown. OCB Output The APL3516A/B/C/D series of power switches provide an open-drain output to indicate that a fault has occurred. When any of current-limit or over-temperature protection occurs for a deglitch time of tD(OCB), the OCB goes low. Since the OCB pin is an open-drain output, connecting a resistor to a pull high voltage is necessary. Copyright ANPEC Electronics Corp. Rev. A.6 - Jun., 2011 11 www.anpec.com.tw APL3516 Application Information Input Capacitor A 1µF ceramic bypass capacitor from VIN to GND, located near the APL3516, is strongly recommended to suppress the ringing during short circuit fault event. Without the bypass capacitor, the output short may cause sufficient ringing on the input (from supply lead inductance) to damage internal control circuitry. Output Capacitor A low-ESR 150µF aluminum electrolytic or tantalum between VOUT and GND is strongly recommended to reduce the voltage droop during hot-attachment of downstream peripheral. Higher-value output capacitor is better when the output load is heavy. Additionally, bypassing the output with a 0.1µF ceramic capacitor improves the immunity of the device to short-circuit transients. Layout Consideration The PCB layout should be carefully performed to maximize thermal dissipation and to minimize voltage drop, droop and EMI. The following guidelines must be considered: 1. Please place the input capacitors near the VIN pin as close as possible. 2. Output decoupling capacitors for load must be placed near the load as close as possible for decoupling highfrequency ripples. 3. Locate APL3516 and output capacitors near the load to reduce parasitic resistance and inductance for excellent load transient performance. 4. The negative pins of the input and output capacitors and the GND pin must be connected to the ground plane of the load. 5. Keep VIN and VOUT traces as wide and short as possible.
