Maxim Integrated MAX6466XR22+ Voltage Monitor

The Maxim Integrated MAX6466XR22+ is a highly precise, low-power voltage monitor designed to ensure the reliability and stability of your electronic systems. This compact component is an essential piece of hardware for monitoring the supply voltage of microprocessors (µPs), microcontrollers (MCUs), and other voltage-sensitive devices, providing a robust solution for system monitoring and protection.

With a fixed factory-set threshold voltage of 2.2V, the MAX6466XR22+ offers a precise monitoring solution that is suitable for a range of applications. This voltage monitor is particularly useful in systems that require a dependable watchdog for safe operation, such as portable/battery-powered equipment, computers, controllers, and intelligent instruments.

The device features a variety of key specifications that make it a versatile and reliable choice for designers. Among its features are:

• Low Quiescent Current: The MAX6466XR22+ is designed for energy-efficient operation, drawing minimal power with a low quiescent current, making it ideal for battery-operated devices.
• High Threshold Accuracy: It offers a precise threshold accuracy of ±1.5% over the entire temperature range, ensuring reliable voltage monitoring under varying conditions.
• Immunity to Short Voltage Transients: The device is built to tolerate brief voltage dips without triggering a false alarm, thereby enhancing system stability.
• Manual Reset Input: It includes a manual reset input that allows for an external override, giving users additional control over the monitoring process.
• Compact SOT23 Package: The MAX6466XR22+ comes in a small SOT23 package, saving valuable board space in space-constrained applications.

In addition to these features, the voltage monitor offers an open-drain RESET output, which remains asserted for a minimum of 140ms after VCC has risen above the reset threshold, providing a reliable startup delay for connected devices. This ensures that the system has adequate time to stabilize before normal operation commences.

Overall, the Maxim Integrated MAX6466XR22+ is a robust and precise solution for voltage monitoring, helping to safeguard your electronic systems against the dangers of undervoltage conditions. Its combination of accuracy, reliability, and compact form factor makes it an excellent choice for a wide array of applications where power supply stability is crucial.
