Product Overview: MAX6821RUK+T from Maxim Integrated

The MAX6821RUK+T is a sophisticated microprocessor (µP) supervisory circuit designed by Maxim Integrated to monitor power supplies in µP and digital systems. It provides excellent circuit reliability and low cost by eliminating external components and adjustments when used in systems that require voltage monitoring and battery control functions.

Key Features

• Voltage Monitoring: This device offers precision monitoring for 3V, 3.3V, and 5V supply voltages, ensuring that the system is operating within acceptable power ranges.
• Reset Output: The MAX6821RUK+T features an active-low reset output, which provides a guaranteed reset signal for a minimum of 140ms after VCC has risen above the reset voltage threshold. This ensures that the µP starts up in a known state.
• Manual Reset Input: An additional feature is the manual reset input, which allows for a reset to be triggered with an external button or signal, providing an extra layer of control.
• Low Power Consumption: Designed for power-sensitive applications, the MAX6821 consumes only 17µA (typ) of supply current, making it suitable for battery-operated devices.
• Compact Package: The device is available in a small, 5-pin SOT23 package, making it ideal for space-constrained applications.
• Temperature Range: It operates over an extended temperature range of -40°C to +125°C, accommodating various environmental conditions.
