Nisshinbo Micro Devices Inc. Supervisors R3132D30EA-TR-FE

The R3132D30EA-TR-FE is a low voltage detector IC from the R3132x series by Lingto Electronic Limited. It features a built-in delay circuit, high threshold accuracy, and operates with an ultra-low supply current of approximately 0.8µA at 3.0V. The device supports an operating voltage range from 0.8V to 6.0V and allows for fixed detector threshold settings in 0.1V increments between 1.0V and 5.0V, with specific standard values available. This IC generates a reset signal when the supply voltage drops below the set threshold and maintains the reset condition for a fixed delay of approximately 240ms after the voltage returns to a higher level. It offers two output types: Nch open drain and CMOS, and is available in compact SC-82AB and SON1612-6 packages, facilitating high-density mounting on circuit boards. Applications include CPU and logic circuit resets, battery checkers, and power failure detection.
