The is a single low voltage, low power microprocessor µP reset circuit in 4 pin SC-70 package. This microprocessor µP supervisory circuit monitors power supply voltage ranging from +1.8V to +5V while consuming only 3µA of supply current at +1.8V. Whenever VCC falls below the factory-set reset thresholds, the reset output asserts and remains asserted for a minimum reset timeout period after VCC rises above the reset threshold. It has an open-drain active-low reset output. It offers a manual reset input with a longer VCC reset timeout period 1120ms or 1200ms and a shorter manual reset timeout 140ms or 150ms. Typical application includes controllers, intelligent instruments, critical microprocessor µP and microcontroller µC power monitoring and battery powered equipment.
