MAX6365PKA31+T Integrated Circuits (ICs)

PMIC - Supervisors

The MAX6365PKA31+T is a Programmable Supervisory Circuit (PSC) developed by Maxim Integrated in 2020. This device is designed to monitor the power supply and provide an alert signal when the supply voltage drops below or exceeds pre-programmed thresholds. It is one of a growing family of Programmable Supervisory Circuit (PSC) ICs, which are becoming increasingly popular as they allow the designer to set any over- or under-voltage threshold with a high degree of accuracy and precision.

The MAX6365PKA31+T is a single-channel PSC with an integrated time delay circuit. The device is designed to help protect sensitive components and reduce power consumption by alerting the system when an over- or under-voltage condition occurs. The device utilizes two separate voltage detection circuits to detect when the supply voltage is outside of a defined range, with programmable threshold levels from +2.06V to +6.00V.

Application Field

In the modern world today, application fields for the MAX6365PKA31+T are abundant. This PSC can be used in many different systems, from industrial, automotive, and consumer electronics. Its high accuracy and precision make the MAX6365PKA31+T the perfect choice for applications such as power management and battery protection. In addition to its primary purpose of voltage monitoring, the device is also ideal for temperature and motor protection, low-battery indicator and alert, and as a watchdog timer in many different fields.

Working Principle

The working principle of the MAX6365PKA31+T is relatively simple. The device continuously monitors the supply voltage, and if the voltage drops below or exceeds the programmable threshold, the device issues an alert signal. Optionally, a time delay circuit can be enabled to delay the issuance of the alert from 0ms to 12ms. The delay allows extra time for the operating system to power-up an alternate power source, or use other methods to minimize system downtime in the event of a supply voltage failure. This ensures maximum protection for sensitive components.

The device has an integrated open-drain output, and can be configured to source or sink current up to 15mA depending on the chosen setup. This ensures optimum flexibility for the designer in terms of selecting the appropriate power management solution for their applications.
