Modern electronic products have become increasingly sophisticated, with huge integrated circuit systems. As these systems incorporate a variety of circuits that need to be powered, supervisors are used to ensure proper functioning of the system. The MAX6307UK40D2-T supervisor is one such device used to monitor and sequence power supply voltages and power-on resets. It is a type of power management IC (PMIC) that is widely used for embedded applications.

The MAX6307UK40D2-T is an active high system supervisor with an internal voltage supervisor and multiple reset outputs. It can be used as a "one-stop shop" for monitoring multiple power supplies, as it combines both power sequencing and reset functions in one IC. It is a 4-channel supervisor that can monitor 4 different voltage levels and 2 inputs, providing 2 open drain active-high outputs.

The four voltage channels of the MAX6307UK40D2-T supervisor feature high accuracy internal voltage monitors. Each channel features a user-configurable threshold, power-on reset (POR), undervoltage (UVLO) and overvoltage (OVLO) detection. The two input channels of this supervisor can be used to monitor external power management signals, such as power good, on/off button, thermal protection, and more. In addition, this supervisor is equipped with an independent active-high reset output to provide a secondary reset signal, allowing simultaneous monitoring and reset.

The MAX6307UK40D2-T supervisor operates over a wide range of temperatures, from -40°C to +125°C. It is housed in a small 6-pin TDFN package that is just 2.0 x 2.1 mm, making it ideal for applications with limited space and/or weight requirements. The part is also RoHS, WEEE, halogen, and REACH compliant, making it suitable for use in end products for the European Union.

The MAX6307UK40D2-T supervisor is suitable for embedded control and PC/server applications. It is often used in platforms such as single-board computers, storage systems, LCD TVs and monitors, set-top boxes, and more. It can be used to monitor power supplies, as well as provide a reset signal when the power fails or the system requests a reset.

In terms of its working principle, the MAX6307UK40D2-T supervisor compares an external voltage to an internal reference voltage, and sends a reset signal if the external voltage is out of tolerance. The supervisor can also be used to provide power sequencing of multiple power supplies to ensure that the system voltage is within the set range. When the supervisor is activated, the reset pin is held high, and will remain high until the power supplies reach their steady state voltage.

In summary, the MAX6307UK40D2-T is a versatile system supervisor for embedded control and PC/server applications. It offers a comprehensive solution for monitoring multiple power supplies and providing power sequencing and reset functions in one IC. It operates over a wide temperature range and is suitable for use in end products for the European Union. It is a highly reliable choice for applications requiring a compact, power-efficient supervisor IC.
