The MAX6381XR39D2-T is a microprocessor supervisory circuit designed by Analog Devices / Maxim Integrated to monitor power supply voltages. This device operates with a reset threshold voltage of 3.9V and features an active-low, push-pull reset output. It is designed to assert a reset signal when VCC falls below the factory-set threshold and maintains it for a minimum timeout period after VCC rises above the threshold.
Key electrical characteristics include a reset threshold accuracy of ±2.5% over temperature and a minimum reset timeout period of 20ms. The device consumes low power, drawing only 3μA at +1.8V. It is capable of monitoring a single voltage and guarantees the reset output state is valid down to 1V.
Packaged in an SC-70, SOT-323 package, the MAX6381XR39D2-T is suitable for surface mount applications. Its primary function is critical μP and μC power monitoring in applications such as computers, controllers, and portable battery-powered equipment.
