Maxim Integrated MAX6364HUT23-T Microprocessor Supervisory Circuit

The MAX6364HUT23-T from Maxim Integrated is a highly reliable microprocessor (µP) supervisory circuit designed to monitor power supplies and microprocessor activity in digital systems. It provides excellent circuit reliability and low cost by eliminating external components and adjustments when used with 2.3V-powered circuits.

This supervisory circuit ensures that the µP is reset to a known state during power-up, power-down, or brown-out conditions. It also features a debounced manual reset input which allows for a very precise timing operation. The MAX6364HUT23-T is ideal for use in portable equipment, computers, controllers, and intelligent instruments where size and reliability are critical.

Key Features:

• Voltage Monitoring: Accurate monitoring of 2.3V power-supply voltages.
• Reset Output: The device provides an active-low reset output which remains asserted for a minimum timeout period after VCC has risen above the reset threshold level.
• Manual Reset Input: A debounced manual reset input (MR) allows the user to initiate a system reset.
• Power-Supply Transient Immunity: No external components are required for power supply ripple rejection, making the design simple and robust.
• Low Power Consumption: Designed for low power consumption, it is an ideal choice for battery-operated portable devices.
• Compact Package: The MAX6364HUT23-T comes in a tiny 6-pin SOT23 package, which is suitable for space-constrained applications.

This supervisory IC enhances system reliability by performing a single function or a combination of functions including power-on reset control, watchdog timer, and supply voltage supervision. The integrated watchdog timer helps in detecting software failures and initiating system resets in response.

With its precision voltage monitoring capability and built-in features, the MAX6364HUT23-T is a versatile component that can be employed in a variety of applications that require reliable voltage supervision to safeguard the integrity of the system. Maxim Integrated's commitment to quality ensures that this supervisory circuit meets the stringent requirements of the most demanding applications.
