The MAX6447UK46L+T is a supervisor intended for use in electronic systems that need battery-backed voltages for reliable backup power and to ensure system integrity. It is part of the wider family of PMIC – Supervisors, which are power management integrated circuits, specifically designed to monitor and supervise power in different applications. This supervisor provides error-free, fault tolerant power supplies with reliable and hassle-free battery backup.

The MAX6447UK46L+T is an advanced device, capable of supporting multiple power-primary and power-secondary sources. It can be used to monitor various power supplies, including those with adjustable outputs, such as battery chargers, solar-based systems and so on. With its built-in Dual Watchdog Timers, it can provide effective restart conditions, ranging from 1 ms to 15 minutes.

The core features of the MAX6447UK46L+T include a maximum supply voltage of 16V, a quiescent supply current of 2.2µA (max) and a wide operating temperature range of -40°C to +85°C. It has a minimum reset threshold voltage of 2.10V, a maximum reset threshold voltage of 3.87V, and a reset/assert-time delay of 3.2ms (min). It also offers two independent WDTs, which can be programmed in one-shot or periodic mode.

The working principle of the MAX6447UK46L+T lies in its ability to monitor and supervise the power supply rail of an electronic system. It works by continuously detecting the voltage rail it supervises, and triggers a reset command when the voltage rail drops below, or rises above the programmed voltage threshold. It also offers an adjustable reset/assert time delay, which ensures reliable operation in areas with rapid power cycling. This supervisor can be used in various applications, such as automotive, industrial, consumer and medical.

The MAX6447UK46L+T offers a high degree of reliability and flexibility, making it an ideal choice for applications that require robust power management. Its ability to work with multiple power sources makes it well-suited for portable or remote applications, as well as applications that may require frequent or extended power failures. The chip also offers an extensive range of error alarms, making it easier to detect and recover from system errors. It is well-suited for use in battery-backed systems, and with its Dual Watchdog Timers, it can provide reliable system reset options.

In summary, the MAX6447UK46L+T is a reliable supervisor from the family of PMIC – Supervisors, which is able to monitor and supervise electronic systems and trigger a reset command at predetermined voltage levels. It is capable of supporting multiple power-primary and power-secondary sources, and can monitor various power supplies with adjustable outputs. With its low supply current and a wide operating temperature range, the MAX6447UK46L+T offers a high degree of reliability and flexibility for various applications, making it an ideal choice for battery-backed systems.
