Maxim Integrated's MAX6467US22D3+T Voltage Monitor

The MAX6467US22D3+T from Maxim Integrated is a precision, low-power voltage monitor, designed to ensure the reliable operation of microprocessors (µPs), microcontrollers (MCUs), and other voltage-sensitive devices. This component is particularly useful in systems where accurate voltage monitoring is critical, such as in portable/battery-powered devices, embedded systems, and industrial equipment.

Key Features

• Voltage Threshold: The device is factory-set to a threshold voltage of 2.2V, making it suitable for monitoring 2.5V power supplies with a tight tolerance.
• Low Power Consumption: With a quiescent current of only 1µA, the MAX6467US22D3+T is an energy-efficient solution that won't significantly drain the battery or power source.
• Reset Timeout: It features an internally fixed 140ms minimum reset timeout period, providing a reliable reset signal for connected digital components.
• Operating Temperature: The device operates over an extended temperature range from -40°C to +125°C, ensuring stability and performance in harsh environments.
• Package: It comes in a compact SOT-143 package, which is ideal for space-constrained applications.

Applications

• Portable/Battery-Powered Devices
• Embedded Systems
• Data Storage Systems
• Industrial Equipment
• Automotive Systems

The MAX6467US22D3+T voltage monitor is designed with a precision monitoring circuit that guarantees the system's integrity by providing a reset signal to the host processor when the monitored voltage falls below the designated threshold. This reset signal ensures that the processor restarts with correct operation after a brownout condition. Moreover, its low power consumption makes it an excellent choice for power-sensitive applications.

Maxim Integrated's commitment to quality and reliability is evident in the design of the MAX6467US22D3+T, making it a trusted component for designers and engineers looking to safeguard their systems against voltage anomalies. Its ease of integration, combined with a robust feature set, provides a straightforward solution for voltage monitoring challenges.
