MAX6313UK41D2-T

The MAX6313UK41D2-T is a 3.3V precision-micropower reset supervisor with an active-high reset and active-low manual reset outputs. The device is ideal for single-supply systems that require a micropower reset supervisor. The MAX6313UK41D2-T offers an adjustable reset threshold voltage monitoring range from 1.08V to 1.5V and fixed reset timeouts of 250 ms, 500 ms, and 750 ms. The 250-ms and 500-ms reset timeouts can be overdriven in order to obtain faster reset timeouts.

Application Field

The MAX6313UK41D2-T is the best choice for battery-powered systems or those requiring an extremely low-power active-low reset and active-high reset functions. Its 3.3V input and precise adjustment range, extremely low quiescent current, and small SO-8 package make it an ideal fit for such systems.

The MAX6313UK41D2-T can be used to monitor input voltage most commonly in industrial, automotive, and consumer applications. It can also be used to monitor the health of critical digital, analog, and RF systems for overvoltage, undervoltage, or other system faults. The device is feature rich which further makes it ideal for a wide variety of applications.

Working Principle

The MAX6313UK41D2-T functions by monitoring the supply voltage for a set threshold. When the voltage drops below the threshold voltage, the device triggers the active low manual reset. The active-high reset brings a system back to normal from a state of non-operation. The device is powered by a 3.3V input voltage, which is then monitored by an internal precision voltage divider.

The device also features an adjustable reset threshold, which is selected over a range of 1.08V to 1.5V via two external components. The reset timeout feature eliminates the need for a manual reset by holding the reset output active for a predetermined amount of time, allowing the system to remain out of reset until the supply voltage returns to a valid level.

The MAX6313UK41D2-T also offers an overdrive mode which allows the device to switch outputs quicker, improving the reset characteristics. This makes the device suitable for use in low-power systems with stringent reset requirements. A short pulse on the manual reset input overrides all internal logic, bringing the system into a known state.

The MAX6313UK41D2-T is an excellent choice for monitoring the health of critical systems. Its combination of low power consumption, high accuracy, and numerous features make it suitable for a wide range of applications.
