The MAX708CUA-T is an advanced multiple output, low power reset and supervisory circuit designed for use in microprocessor-based systems. It monitors the supply voltages and the application system, and provides a reset signal in the event of a power or microprocessor system fault. The MAX708CUA-T is available in a 4-pin SOT-23 package, making it an ideal choice for space-constrained and portable applications. In this article, we will discuss the application field and working principle of the MAX708CUA-T.

The MAX708CUA-T is primarily intended for use in microprocessor-based systems and supervisory circuits. It is used to monitor the supply voltages and the application system, and to reset the microprocessor system when a fault is detected. It is available in a 4-pin, SOT-23 package, making it suitable for use in small devices and portable applications. Additionally, it is powered by a single 1.8V supply voltage and features a low quiescent current consumption of only 10 microamps. This makes it an ideal low-power solution for microprocessor-based systems.

The MAX708CUA-T features a reset output (RESET#) and an output enable (O/E#) pin. The reset output is a, active low, open-drain reset signal that is asserted whenever a fault is detected by the device. The output enable pin is used to enable and disable the reset signal. Both the reset output and output enable pins are fully over-voltage protected.

In addition to the reset and output enable pins, the MAX708CUA-T features an enable (EN#) pin. The enable pin is used to enable and disable the device. When the enable pin is high, the device is active and monitoring the supply voltages and application system. When the enable pin is low, the device is disabled and the reset output and output enable pins are tri-stated. Additionally, the device features an adjustable reset threshold voltage. This allows the user to set the reset threshold for the device to any desired value, allowing for greater flexibility when used in different applications.

The MAX708CUA-T is capable of monitoring both rising and falling supply voltages, protecting against over-voltage in either direction. It is also capable of monitoring the state of the application system, with a programmable reset timeout of up to 10.24 seconds. This allows the device to protect against system faults due to software, hardware, or power supply issues.

The MAX708CUA-T is a versatile reset and supervisory circuit that is capable of monitoring both rising and falling supply voltages and the application system. It is an ideal choice for low-power micro-processor based applications due to its small form factor and low power consumption. Additionally, its adjustable reset threshold voltage allows it to be used in a variety of applications.

In summary, the MAX708CUA-T is an advanced multiple output, low power reset and supervisory circuit designed for use in microprocessor-based systems. It offers an adjustable reset threshold voltage, reset timeout, and low power consumption, making it an ideal choice for low-power microprocessor-based applications.
