MAX1607ESA+T

Updated: 2026-07-23

Overview

The MAX1607ESA+T is a precision voltage detector designed for monitoring power supplies in electronic systems. Manufactured by Maxim Integrated, this device ensures reliable operation by resetting microprocessors or other logic circuits when voltage levels fall below a specified threshold. Its compact SOT-23 package makes it suitable for space-constrained applications. The device is widely used in industrial, automotive, and embedded systems, where stable voltage supervision is critical. With adjustable threshold voltages and low quiescent current, the MAX1607ESA+T provides flexibility and efficiency in power management applications.

Structure and Working Principle

The MAX1607ESA+T consists of a voltage reference, comparator, and output driver. It continuously monitors the input voltage and compares it to a user-adjustable threshold. When the input voltage drops below this threshold, the device asserts a reset signal to ensure proper system initialization. The adjustable threshold is set using external resistors, allowing customization for specific applications. The low quiescent current (typically 5µA) minimizes power consumption, making it ideal for battery-powered devices.

Key Features

The MAX1607ESA+T offers several key features, including an adjustable reset threshold (1.6V to 5.0V), low quiescent current, and a compact SOT-23 package. These features make it a versatile choice for voltage monitoring in various electronic systems. Additionally, the device provides a manual reset input, allowing for external system reset control. Its wide operating voltage range (1.6V to 5.5V) ensures compatibility with a broad spectrum of applications.

Application Areas

The MAX1607ESA+T is commonly used in industrial control systems, automotive electronics, and embedded computing. Its precision voltage monitoring capability ensures reliable operation in environments where power supply fluctuations are a concern. In automotive applications, the device is used to monitor battery voltage and reset microcontrollers during power-up or brownout conditions. In embedded systems, it provides critical voltage supervision for microprocessors and FPGAs.

Maintenance and Precautions

To ensure optimal performance, the MAX1607ESA+T should be operated within its specified voltage and temperature ranges. Proper PCB layout and grounding are essential to minimize noise and ensure accurate voltage monitoring. Avoid exposing the device to excessive current or voltage spikes, as this may damage the internal circuitry. Regular testing and calibration of the reset threshold are recommended for critical applications.

B2B Procurement Guide

When procuring the MAX1607ESA+T, consider factors such as lead time, minimum order quantity, and supplier reliability. Maxim Integrated and authorized distributors are recommended sources to ensure genuine components. Bulk purchasing may offer cost savings, but verify storage conditions to prevent damage to the devices. Always check for the latest datasheet and application notes to ensure compatibility with your design.
