The MAX6307UK45D2+T is an active-low, push-pull reset IC with a 4.5-V reset threshold voltage. It provides reset validation period of 200 ms and is available in the small 8-pin SOIC (D2) package. This active-low reset output can be used to reset complex systems such as microprocessors or in critical field applications where reset accuracy and timing are important. The device is an ideal reset supervisor for critical system designs where reliable reset operations are essential for a long operational lifetime.

The MAX6307UK45D2+T belongs to the PMIC (Power Management IC) Supervisors category, and is designed especially for the low voltage field applications. The device can provide real-time monitoring of system’s power and temperature levels, and can be used for reset and power-on sequencing. The device supports step-down operate VCC, manual reset input as well as VCC out current exceeds. It also offers an up to 30-ms reset validation period eliminating the majority of power-up faults. The device can operate over a wide temperature range of −40°C to +125°C.

The working principle of MAX6307UK45D2+T is inspired by the Under Voltage Lock Out (UVLO) technology. It uses an internal voltage tracker to detect and prioritize system voltages in a microprocessor based system. It can detect minimum, maximum and no-load operating voltages; when an Under Voltage fault occurs, it forces the reset and clears the fault condition. If a valid fault condition is encountered, the device will stay in reset until the fault condition is cleared. Additionally, the device offers an extra reset feature, allowing the user to manually force a reset from an external input.

The MAX6307UK45D2+T provides a 5-V low-voltage reset output. This active-low reset output is internally connected to a push-pull logic configuration which enables a fast reset response time. It has a reset time-out period of 200 ms, and a reset cycle time of 8 ms typical. It provides an up to 30-ms reset validation period that eliminates the majority of power-up faults. The device also offers an active-high, open-drain reset-VCCLL output that remains active when VCC is above 4.5 V.

Its main application field is in microprocessor and/or complex system which requires high reset accuracy and timing. It also finds application in critical field applications where reset accuracy and timing are important, such as in automotive and consumer electronics. Additionally, it can be used in power distribution and management applications, as a reliable reset solution for power, temperature, and time-based microprocessor-based system.

The MAX6307UK45D2+T is an ideal supervisor IC for critical system designs, offering reliable reset operations and accurate reset timing. Its unique design, which is inspired by the Under Voltage Lock Out (UVLO) technology, allows it to detect and prioritize system voltages in microprocessor-based systems. It is highly reliable, accurate and can work in a variety of applications, making it one of the best supervisors available in the market today.
