MAX795RESA+T is a complete, low-cost, microprocessor supervisory circuit which contains two separate voltage monitors and one active-high reset output. It is designed to monitor positive voltages, ranging from +2.8V to +10.9V, to ensure that the microprocessor voltage supply remains in the prescribed range. This IC is also equipped with a precision voltage reference, a window detector and a temperature-grade switch to guarantee accuracy and performance over a wide temperature range.

The MAX795RESA+T is an excellent choice for resetting microprocessor-based systems. Its wide range of features can be used to control the flow of power to the system, determining when the processor must be reset, and ensuring that the voltage remains within acceptable limits throughout its life. This device is ideally suited to the control of power supplies, battery-operated and standby systems, and rugged systems requiring robust, reliable control.

This IC incorporates two monitored voltages, allowing the user to monitor a single or multiple power supplies, as well as monitor the battery voltage. A voltage window detector is included in the device, which assures accurate monitoring of the supplies within the preset window. This window must be programmed using the voltage adjust pins for each voltage. In addition, a temperature-grade switch is included to ensure accurate monitoring over the full operating temperature range.

The reset output, active-high, is designed to reset the microprocessor. This output has an adjustable threshold. It is also able to generate a low-voltage reset signal, if necessary. If the monitored voltage drops below the specified threshold, an output signal is generated and the reset pulse is sent to the microprocessor. The reset pulse is independent of the supply voltage, so the output remains active and the microprocessor is reset as long as the monitored voltage remains below the specified threshold. In addition, the reset output is adapted to withstand longer duration current drives.

The MAX795RESA+T is an ideal choice for many kinds of microprocessor-based systems. It offers an exceptional combination of features, providing excellent protection and reliability in a small, cost-effective IC. This device is an excellent choice for a wide variety of applications, such as battery-operated systems, systems with multiple power supplies, autostart systems, high-performance system designs, and rugged applications requiring reliable voltage monitoring and reset control.
