Maxim Integrated MAX6377UR30+T Voltage Detector

The Maxim Integrated MAX6377UR30+T is a precision microprocessor (μP) reset circuit that monitors the power supplies in digital systems. This highly reliable component ensures that the system's microprocessor and other ICs initialize in the correct state during power-up, power-down, or brown-out conditions. The MAX6377UR30+T is an essential device for maintaining system integrity and preventing data corruption or erratic system behavior due to inadequate power supply voltages.

This voltage detector operates over a wide voltage range and is particularly suited for battery-operated equipment with its low power consumption. The device features a factory-trimmed reset threshold voltage of 3.0V, which is ideal for 3.3V-powered systems. The reset output is asserted when the VCC supply voltage falls below the reset threshold and remains asserted until VCC rises above the reset threshold for the reset timeout period.

With its tiny SOT-23 package, the MAX6377UR30+T is optimized for space-constrained applications. Its small footprint does not compromise its performance, as it also offers excellent temperature stability and low supply current. Moreover, the device is designed to reject brief transients on the VCC line, providing a stable reset signal even in noisy environments.

Key features of the MAX6377UR30+T include:

• Factory-Set Reset Threshold Voltages for 3.0V Systems
• 140ms (min) Reset Timeout Period
• Low 1.2μA Supply Current
• Wide Operating Voltage Range
• Immunity to Short VCC Transients
• Push-Pull RESET Output

The MAX6377UR30+T is an ideal solution for portable devices, computers, controllers, and intelligent instruments that require precise monitoring of the power supply to ensure proper operation. Its high level of integration and ease of use make it a popular choice among engineers and system designers looking for a reliable voltage monitoring solution.
