MAX814NEPA+ Application Field and Working Principle

The MAX814NEPA+ (MAX814) is an inexpensive, low-power supervisor and voltage monitor integrated circuit developed by Maxim Integrated of San Jose, California. This device is designed to improve the power management, reliability and safety of electronic systems.

MAX814 is a single-channel voltage monitor and supervisor device. It uses a single-ended input to measure the power supply voltage and is well-suited for battery-powered systems. The device also includes an open-drain output that is used to provide an indication to the controlling microprocessor or logic when the power supply has exceeded an overvoltage or undervoltage threshold. The supply voltage is monitored by a precision analog-to-digital converter and other features such as a power-on reset (POR) and manual reset are included.

The MAX814NEPA+ can be used in many types of systems such as cellular phones, point-of-sale power systems and notebook computers. It is particularly well-suited for applications requiring a highly reliable system with minimal power dissipation and minimal board space requirements. The device also has several advantages over other voltage monitoring ICs, such as lower current consumption and a wide operating temperature range (-40 to +85 ˚C).

The MAX814NEPA+ measures the supply voltage (VIN) by an onboard A/D converter. The output from the A/D converter is compared to the upper or lower trip points (VOUTL or VOUTH) programmed via the bias resistors. If the supply voltage falls below the lower trip point (VOUTL), the device outputs a low voltage to reset the system via its RESET pin. Similarly, if the supply voltage rises above the upper trip point (VOUTH), the device outputs a high voltage to reset the system via its RESET pin. The hysteresis voltage of the device is adjustable by a pair of bias resistors.

The MAX814NEPA+ is a low-power device and consumes nearly 60μA at 25˚C when operating with a 5V supply. This low-power operation allows it to be used in battery-powered systems without significantly impacting the battery life. The device also has an active-low RESET output that is open-drain, so multiple devices may be connected in parallel for applications requiring multiple reset thresholds.

The MAX814NEPA+ is an ideal choice for providing power management, reliability, and safety for a variety of applications. It has a wide operating temperature range, low power consumption, and a programmable reset threshold for overvoltage and undervoltage conditions. This device is designed to improve the power management, reliability, and safety of electronic systems.
