Product Overview: MAX876BCSA+T by Maxim Integrated

The MAX876BCSA+T is a high-performance, low-power, serially interfaced, microprocessor (µP) supervisory circuit from Maxim Integrated, designed to monitor power supplies in digital systems. It provides excellent circuit reliability and low cost by eliminating external components and adjustments when used with +5V-powered circuits.

This device performs a single function: it asserts a reset signal whenever the VCC supply voltage declines below a preset threshold, keeping it asserted for at least 140ms after VCC has risen above the reset threshold. The reset output is available in either an active-high or active-low configuration, making it versatile for different system design requirements.

The MAX876BCSA+T comes in a compact 8-pin SOIC package, which is suitable for space-constrained applications. It operates over a wide temperature range from -40°C to +85°C, ensuring reliability in various operating environments. Its low supply current of 4µA (typical) makes it an ideal choice for portable and battery-powered applications.

Key features of the MAX876BCSA+T include:

• Precision monitoring of +5V power-supply voltages.
• Fully specified over temperature.
• Reset threshold suited for +5V-powered systems.
• 140ms (min) power-on reset pulse width.
• Low supply current of 4µA (typical).
• Active-high or active-low reset output options.
• 8-pin SOIC package for compact footprint.

The MAX876BCSA+T supervisory circuit is an essential component for managing system integrity. It ensures that microprocessors, microcontrollers, and other digital systems remain within safe operating conditions by providing a reliable reset signal during power-up, power-down, and brown-out conditions. Its integration into a system helps to prevent code execution errors, memory corruption, and other power-related failures that can occur when the supply voltage falls out of the acceptable range.

Maxim Integrated's reputation for quality and reliability is reflected in the MAX876BCSA+T, making it a trusted choice for engineers and designers looking to enhance the safety and stability of their digital systems.
