MAX6383XR44D3+T

Supervisors Overview

The MAX6383XR44D3+T is a single-channel voltage supervisory circuit from the MAX6383 series, manufactured by Analog Devices Inc. (Maxim Integrated). It operates within a supply voltage range of 1.8 V to 5 V with a maximum rating of 5.5 V. The device features a fixed reset threshold of 4.4 V and an overvoltage threshold of 4.41 V. It provides an active-low, open-drain output with a reset delay time of 2.4 s. The component consumes 7 µA of operating current and functions across a temperature range of -40°C to +125°C. It is housed in a compact SC-70-3 surface-mount package.

Supervisors Feature Summary

• Monitors power-supply voltages using a factory-set threshold without requiring external components.
• Provides an active-low open-drain reset signal that asserts when input voltage falls below the specified limit.
• Maintains low power consumption suitable for battery-operated applications.

Supervisors Applications

• Microprocessor system supervision
• Portable equipment power management
• Battery-powered consumer electronics
