MAX6373KA supervisors are integrated circuit devices which are used to monitor the system or chip power supply. The device produces a reset once it detects one of parameters (e.g. voltage, temperature) has gone out of the specified threshold values. This reset is used to protect the system from potential damaging caused by over-voltage or over-temperature conditions. The MAX6373KA supervisors are especially useful in high reliability applications where reset is needed to ensure proper functioning.

To ensure the board performs reliably and that the device will reset when necessary, it is important to design the power supply properly. The MAX6373KA supervisor has two input voltage ranges, a selectable voltage, and a Trip Point Accuracy specification. The Trip Point Accuracy is the difference between the voltage from the Vcc pin and the Voltage-On Detection (VOD) or Voltage-Off Detection (VOD) thresholds that control the power reset.

The MAX6373KA uses a typcal comparator, voltage divider circuit and bandgap reference, as well as four external capacitors, two resistors and two transistors to detect the VOD and VON thresholds. An advantage of this supervisor is that it can take either an open drain output or an open collector/NPN output, depending on the application. This allows the MAX6373KA to be used in a variety of applications.

The MAX6373KA supervisor has an internal level-shifting circuit, which makes it possible to use the device to monitor dual supplies, like the two voltage sources used in dual core CPUs, or single supply systems with additional supply levels. Unlike other supervisors, the MAX6373KA includes a time delay between the Vcc pin and the VON. This allows for more time for the primary supply to stabilize before activating the reset.

The MAX6373KA supervisor has many useful features, like an active-low TTL or CMOS reset or an output that can be connected to the system interrupt. The MAX6373KA is used in a variety of different applications, from low-power, single voltage systems to dual-supply, high-power systems used in industrial and automotive systems. It can also be used to monitor a wide range of parameters, from sensitive electronic components to temperature, current, and voltage levels.

The MAX6373KA supervisor is one of the most reliable and advanced supervisors available. It has features that ensure it will perform reliably and provide the necessary reset protection in a wide range of applications. With its active-low reset output and integrated delay features, the MAX6373KA supervisor is an excellent choice for high reliability applications.
