The DIO8030 is micro-processor (μP) supervisory circuits that are used to monitor the power supplies in μP and digital systems. The circuits provide excellent reliability. The DIO8030 has an active-low reset output to perform a single function: assert a reset signal whenever the VCC supply voltage rises above a preset threshold and keeping it asserted for at least 8 ms. The DIO8030 has an open-drain output which requires an external pull-up resistor connected to power supply. This feature offers high flexibility to reset systems with various supply voltages. The reset comparator is designed to ignore fast transients on VCC, and the outputs are guaranteed to be in the correct logic state for VCC down to 1.0 V over the temperature range. The device is available in 3-pin SOT23 and SOT23-3 packages.
