Maxim Integrated MAX8213BCSE Product Overview

The MAX8213BCSE is a high-performance microprocessor (µP) supervisory circuit designed by Maxim Integrated to monitor power supplies in digital systems. It provides excellent circuit reliability and low cost by eliminating external components and adjustments when used in conjunction with single power-supply systems.

This supervisory circuit ensures that the µP is reset to a known state during power-up, power-down, and brownout conditions. The MAX8213BCSE monitors the power supply voltage of a µP or other digital system and generates a reset pulse when the supply voltage drops below a preset threshold. The reset output remains asserted for a period of time after the supply voltage has risen above the reset threshold, ensuring the µP has adequate time to stabilize during power-up.

The device is housed in a compact 16-pin narrow SO package, making it suitable for space-constrained applications. Its low power consumption and wide operating voltage range make it an ideal choice for portable and battery-powered equipment.

Key features of the MAX8213BCSE include:

• Precision Voltage Monitoring: Accurate monitoring of the power supply voltage to ensure reliable operation of digital systems.
• Programmable Reset Timeout: The reset timeout period can be programmed by an external capacitor, allowing designers to customize the reset delay for specific applications.
• Low Power Consumption: Designed for energy efficiency, it is suitable for battery-powered devices.
• Wide Operating Voltage Range: Compatible with a variety of digital systems, supporting a broad range of supply voltages.
• Manual Reset Capability: Includes a manual reset input, allowing for a system reset to be triggered by external hardware or software events.
• Debounced TTL/CMOS-Compatible Inputs/Outputs: Ensures clean interfacing with other digital components without requiring additional external debounce circuitry.

The MAX8213BCSE from Maxim Integrated is a robust solution for microprocessor system monitoring, offering protection against unpredictable conditions that could lead to system failure. Its ease of integration and dependable performance make it an excellent choice for a wide array of applications, from industrial controls to consumer electronics.
