Overview: S-19721 Series www.ablic.com © ABLIC Inc., 2023 AUTOMOTIVE, 125°C OPERATION, 36 V INPUT, 250 mA VOLTAGE TRACKER WITH REVERSE CURRENT PROTECTION
Rev.1.0_00 This IC, developed by using high-withstand voltage CMOS process technology, is a voltage tracker with a reverse current protection function, which has high-withstand voltage and low current consumption. Since the maximum operating voltage is as high as 36 V and the current consumption is as low as 40 μA typ., it contributes to the reduction of standby current. This IC operates stably due to the internal phase compensation circuit so that users are able to use low ESR ceramic capacitor as the output capacitor. This IC includes an overcurrent protection circuit that prevents the load current from exceeding the current capacity of the output transistor and a thermal shutdown circuit that prevents damage because of overheating. Due to the built-in reverse current protection function, the reverse current flowing from the VOUT pin to the VIN pin can be controlled as the small value −5 μA min. Therefore, IC protection diode is not needed.
ABLIC Inc. offers a "thermal simulation service" which supports the thermal design in conditions when our power management ICs are in use by customers. Our thermal simulation service will contribute to reducing the risk in the thermal design at customers' development stage. ABLIC Inc. also offers FIT rate calculated based on actual customer usage conditions in order to support customer functional safety design. Contact our sales representatives for details.
