Product Overview: MAX6329ZHUT+T from Maxim Integrated

The MAX6329ZHUT+T is a precision, low-power microprocessor (µP) supervisory circuit designed by Maxim Integrated to monitor power supplies in µP and digital systems. It provides a significant level of system reliability through its reset and watchdog functions, ensuring that the µP resets to a known state during power-up, power-down, or brown-out conditions. Available in a compact, 5-pin SOT23 package, this device is ideal for space-constrained applications.

Key Features

• Voltage Monitoring: The MAX6329ZHUT+T offers precise monitoring of the power supply voltage with a factory-set reset threshold voltage, ensuring reliable operation and protection for the system.
• Low Power Consumption: Designed for power-sensitive applications, this supervisory circuit consumes minimal power, with a typical supply current of only 5.5µA, making it suitable for battery-operated devices.
• Reset Output: This device provides a reset output which remains asserted for a minimum of 140ms after VCC has risen above the reset threshold, ensuring the µP has sufficient time to stabilize before resuming operation.
• Watchdog Timer: With an integrated watchdog timer, the MAX6329ZHUT+T can monitor software execution and system activity, providing an additional layer of system reliability.
• Temperature Range: It operates over an extended industrial temperature range of -40°C to +125°C, making it versatile for various industrial applications.
