Maxim Integrated MAX6714BUB - Quad Voltage Monitor

The Maxim Integrated MAX6714BUB is a compact, highly precise quad voltage monitor designed to ensure the reliable operation of microprocessor (µP) systems. This device is engineered to monitor multiple supply voltages and assert a reset signal whenever any of the monitored voltages fall below their respective factory-set thresholds. The MAX6714BUB is ideal for a variety of applications, including computers, controllers, and intelligent instruments, where accurate voltage monitoring is critical for system integrity.

This voltage monitor comes in a tiny microMAX-10 package, making it an excellent choice for space-constrained applications. It operates over a wide voltage range, from 1.8V to 5.0V, which makes it versatile for different system designs. The MAX6714BUB features four voltage detector inputs, each with its own voltage threshold. These thresholds are precisely factory-set and can monitor voltages as low as 1.25V.

One of the key features of the MAX6714BUB is its manual reset input, which provides a means to initiate a system reset manually. This input is debounced to eliminate any spurious resets caused by noise or contact bounce in the reset pushbutton. Additionally, the device offers an active-low reset output, which remains asserted for a minimum of 140ms after all voltages have returned to acceptable levels, ensuring a proper system reset.

The MAX6714BUB also includes an active-low watchdog input that, when left unconnected or driven low, disables the watchdog timer to prevent unwanted system resets during normal operation. When the watchdog input is driven high, the internal watchdog timer is enabled, monitoring the system for software faults or other malfunctions.

Overall, the Maxim Integrated MAX6714BUB provides robust protection for your system by continuously monitoring supply voltages and ensuring that your system operates within safe voltage thresholds. Its small size, precision, and feature set make it an indispensable component for any critical system requiring reliable voltage monitoring.
