The MAX6725KASVD3+T is a supervisory device, designed to support high precision power management and system level monitoring needs. This state-of-the-art device combines two main application fields: voltage monitoring and system reset, in a very low power consuming and integrated module.

Application Field

The MAX6725KASVD3+T is mainly used to monitor and manage the power supply and to facilitate system reset on the one hand, while providing the necessary interface communication protocol to facilitate the effective system integration on the other.

The device consists of a voltage supervisor designed to monitor and control circuit input voltage levels applicable to Digital Signal Processors (DSPs); a wide temperature range precision voltage reference and a watchdog timer. The supervisor provides very accurate circuit monitoring, and is able to detect different voltage levels ranging from 0.8V up to 5.5V. Moreover, the device is able to provide flexible reset outputs, including fixed cyclical, or timer-based reset sequences.

The device provides comprehensive reset functionality, as well as other important features such as an active high reset, active low reset, manual reset and a watchdog timer. All these features are commonly used in wide variety of systems, such as personal computers, process finishers, and other power and processor-controlled devices.

Working Principle

The MAX6725KASVD3+T features a dual input Voltage Supervisor and a wide temperature range voltage reference. The voltage supervisor can monitor up to two voltages for over/under voltage conditions, and generate alerts to indicate problems that could adversely affect the device’s operation. Furthermore, the device can be configured to automatically reset in the case of a voltage fault or watchdog timer overflow.

The device also provides an adjustable reset delay for both active low and active high resets. The delay is adjustable from 0-10 seconds to accommodate different kinds of processor reset requirements. Additionally, it provides a manual reset option, which can be triggered with an external signal.

The device’s wide temperature range precision voltage reference ensures that the device’s monitoring accuracy is independent of temperature changes. Furthermore, the device features programmable watchdog timeout periods, enabling the device to detect system hangs and initiate a reset.

The MAX6725KASVD3+T provides a variety of configuration options. The device can be programmed to assert either active high or active low reset signals during alarm or watchdog timer events. Furthermore, it can operate in autonomous or open-drain modes. The device also features a power-on reset delay, which can be programmed individually for active high, active low and manual reset signals.

The device is designed to be very low power consuming, using typically less than 5µA of shutdown current. This allows for effective power saving in systems where battery life is important. Finally, the device provides an LED output which can be used to indicate the state of the voltage supervisor and reset signals.
