A supervisor or voltage supervisor is an Integrated Circuit (IC) that helps operate and supervise the reset initiation level of the power supply within a system. Supervisors are a vital element of maintaining reliable and proper operation of a system; routinely used in fault monitoring and handling of hardware functions. The MAX706SCUA+T IC is a supervisor that uses a programmable reset initiation threshold to ensure proper system reset and power-on reset operations.The MAX706SCUA+T is a precision voltage supervisor with a built-in fixed reset threshold of 4.63V (adjustable in 50mV steps). This supervisor contains a reset output which switches multiple logic levels compatible with Intel’s D3 and D0 states. The MAX706SCUA+T provides an accurate reset threshold across a wide temperature range (-40° to +85°C). The device has a factory-calibrated output hysteresis. This ensures that the output switches between the active and inactive states without oscillation.The primary application field of the MAX706SCUA+T is to monitor power supplies and power supply sequencing logic. This supervisor is able to monitor a wide range of voltages, and offers the flexibility necessary to anticipate multiple functions and configurations of the power supply design. For instance, the MAX706SCUA+T can be used in Battery-Backed Applications to control autload circulation. The supervisor monitors the battery voltage, initiating a reset if the voltage level falls below the threshold. This helps ensure system stability and reliability, while simplifying the debounce circuit design of the power system.The MAX706SCUA+T IC has a few different working principles. The pin can monitor an auxiliary voltage or an internal voltage or it can be used as an active-high reset with manual reset output. During its normal operating state, the pin stays active. When the voltage falls below the programmable threshold, the pin is deasserted. In this mode, the supervisor first monitors the input voltage, then waits for the timer to expire for the output to be asserted.The reset timeout period can also be programmed with the MAX706SCUA+T. The timer duration is set using a resistor value and an external capacitor, which determines how long the output will remain in the reset state before triggering an active output. The IC can be programmed to timeout in a range from 0.1 seconds to 10 seconds. This helps to ensure system reliability, as the supervisor can check reset status multiple times over a period of time.The MAX706SCUA+T is a low-power supervisor IC with a low quiescent current dissipation of 10μA. The device offers a wide input voltage range, from 2.1V to 5.5V, which makes it possible to use this supervisor for systems with different power supplies such as AC, DC or USB. Additionally, the MAX706SCUA+T has Separate Active-High and Active-Low output pins which enable it to be used in various systems and enable easy connection to other ICs.The MAX706SCUA+T IC is suitable for a wide range of applications, including battery-backed applications, power sequencing, and industrial, telecom, and consumer systems. This supervisor is also very useful for any application that requires an accurate reset threshold in order to ensure system stability and reliability.In conclusion, the MAX706SCUA+T is a highly reliable, programmable, and low-power voltage supervisor. Thanks to its programmable threshold and timeout period, this supervisor is suitable for many applications. Its low power consumption makes it ideal for systems that need a constant power supply in order to ensure reliability. It is also easy to use and allows system designers to easily set up the threshold and timeout period in order to ensure a stable system operation. With its robust features and reliability, the MAX706SCUA+T is a great addition to any system.
