MAX6389XS44D3+T

The MAX6389XS44D3+T is a dual 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 has an auxiliary input for monitoring a second voltage. Typical application includes controllers, intelligent instruments, critical microprocessor (µP) and microcontroller (µC) power monitoring and battery powered equipment.
