When the junction temperature exceeds +160 oC, the over-temperature protection operating properly. The UVLO circuit has a hysteresis and a de-glitch feature so that it will typically ignore undershoot transient on the input. circuitry disables the LDO outputs, allowing the device to cool down. The LDO outputs are enabled again after the Soft-Start (For Each Channel) junction temperature cools down by 40 oC, resulting in a pulsed output during continuous thermal overload The APL5535 provides an internal soft-start circuitry to control rise rate of the output voltage and limit the current conditions. Over-temperature protection is designed to protect the IC in the event of over temperature conditions. surge during start-up. The output voltage starts the softstart at approximate 60µs after the VIN is over the UVLO For reliable operation, the junction temperature cannot exceed TJ=+125oC threshold. The typical soft-start interval is about 60µs. Current-Limit Protection (For Each Channel) The APL5535 provides a current-limit protection function. During current limit, the device limits output current at current limit threshold. For reliable operation, the device should not be operated in current limit for extended period. Short-Circuit Current-Limit Protection (For Each Channel) When the output voltage drops below 0.8V, which is caused by the over load or short circuit, the device limits the output current down to a safe level. The short circuit current limit is used to reduce the power dissipation during short circuit conditions. If the junction temperature is over the over-temperature threshold, the device will enter the thermal shutdown. Enable/Disable (For Each Channel) Pulling the V EN1/2 above 1.5V enables the respective LDO output, and pulling V EN1/2 below 0.4V disables the respective LDO output. When both the LDO outputs are disabled, the supply current is reduced to less than 1µA. EN1/2 pins are internally pulled low by resistors. If shutdown function is not used, connect EN1/2 to VIN for normal operation. The enable inputs are compatible with both TTL and CMOS logic levels. Copyright ANPEC Electronics Corp. Rev.
