MAX807MCWE+T

The MAX807MCWE+T is a highly integrated power management integrated circuit (PMIC) designed to safely monitor and restart microprocessor-based systems in the event of power outages. It features low-power operation, continuous monitoring of the supply voltage, adjustable output voltage, and an adjustable watchdog timeout period. As a member of the Supervisors family of Power PMIC products, the MAX807MCWE+T provides safe, reliable power management and control for a variety of applications.

The MAX807MCWE+T can be used for a range of applications, including processor power-on control, reset generation, and fault monitoring. It is suitable for use in embedded systems, control equipment, industrial automation and consumer safety products where reliable power management and continuous monitoring of the system supply voltage are required.

The MAX807MCWE+T is a low-power and highly integrated PMIC, which is ideal for use in cost and space sensitive applications. It is packaged in a 17-pin TSSOP package, and has a wide supply voltage range from 2.25V to 19V. With its low quiescent current of 30μA (TYP), it requires minimal power to operate and is more energy efficient than most other PMICs.

The MAX807MCWE+T is a supervisor IC with an integrated reset circuit that monitors the input voltage and provides an output when the input voltage drops below a predefined value. The reset circuit can be configured with adjustable voltage thresholds and reset delay time, allowing the user to adjust the thresholds to the desired levels. Once the threshold is reached, the reset output will be asserted, and the device will remain in reset until the supply voltage is again within the acceptable range.

The MAX807MCWE+T also provides a watchdog timer, which is a timer that can be configured to generate a reset pulse in the event of a system failure. The watchdog timer can be configured to generate an internal reset pulse after a specified period has elapsed in the event of an unintentional, or runaway, program execution. This feature allows the system to be rebooted in the event of a system failure, helping to protect against data corruption.

In addition to the reset and watchdog timer functions, the MAX807MCWE+T also provides a power-on reset (POR) feature. This feature will detect when the power supply voltage rises above a certain threshold, and will then assert a reset signal to start the system. This feature is useful for systems that are occasionally powered off, and need to be reset upon power-on.

The MAX807MCWE+T is an ideal solution for applications that require reliable power management and continuous monitoring of the supply voltage. It offers adjustable voltage thresholds and reset timeouts, a low quiescent current, and a power-on reset feature, making it an ideal choice for embedded and consumer safety applications.
