The FM1233ADS3X is a supervisor circuit designed to monitor microprocessor power supplies and other system voltages, issuing a reset pulse during fault conditions. It supports various threshold voltages, specifically offering a reset threshold of 2.72V, suitable for 3.3V and lower voltage microprocessor systems. The device features a precision temperature-compensated voltage reference and comparator, ensuring reliable operation across a wide temperature range of -40¬8C to +105¬8C. When the supply voltage drops below the threshold, the FM1233ADS3X generates a reset pulse that remains active for approximately 250 ms after the voltage returns to normal, allowing system stabilization. The output is an open-drain active low type, and the device includes internal circuitry for debouncing external pushbutton resets. It is packaged in a compact SOT23-3 format, making it suitable for space-constrained applications. The supervisor circuit is capable of monitoring external reset signals and provides an internal pull-up resistor for added convenience.
