The MAX6327-29W is a precision, low-power microprocessor (µP) supervisory circuit designed by NXP to monitor power supplies in µP and digital systems. It provides a significant level of system reliability and accuracy required for modern electronic applications, ensuring the proper operation of the µP by monitoring the power supply voltage.

Key Features

• Voltage Monitoring: This device offers precise monitoring of the 2.9V power supply voltage, ensuring that the connected microprocessor operates within its specified voltage range.
• Low Power Consumption: Designed for power-sensitive applications, the MAX6327-29W operates with minimal power consumption, making it ideal for portable and battery-operated devices.
• Reset Output: Upon detecting a voltage drop below the factory-set reset threshold, the device asserts a reset signal, which holds the µP in the reset state until the system voltage stabilizes above the threshold, ensuring a proper system startup.
• Manual Reset: It includes a manual reset input that allows for an external trigger to initiate a system reset, providing an additional layer of system control.
• Watchdog Timer: The integrated watchdog timer serves as a system check, preventing system lock-up by resetting the µP if it fails to strobe within a preset time frame.
• Temperature Range: The device operates over an extended temperature range, making it suitable for industrial applications subject to harsh environmental conditions.

Applications

The MAX6327-29W is versatile and can be used in a variety of applications including:

• Portable/Battery-Powered Equipment
