Maxim Integrated MAX6419UK16+T Microprocessor Supervisory Circuits

The MAX6419UK16+T from Maxim Integrated is a compact, highly reliable microprocessor (µP) supervisory circuit designed to monitor power supplies in µP and digital systems. It provides excellent circuit reliability and low cost by eliminating external components and adjustments when used in systems with a 1.6V supply voltage. This supervisory circuit is ideal for use in a wide range of applications, including portable/battery-powered equipment, computers, controllers, and intelligent instruments.

Key Features

• Voltage Monitoring: The device monitors the system voltage and maintains a reset output until the system voltage stabilizes above the reset threshold. It keeps the µP in reset for a minimum of 140ms (typical) after Vcc has risen above the reset threshold, ensuring a proper system reset.
• Low Power Consumption: Designed for power-sensitive applications, the MAX6419UK16+T consumes a low quiescent current of only 1.5µA (typical), maximizing battery life in portable applications.
• Manual Reset Input: It features a manual reset input that allows the user to initiate a system reset, providing an additional layer of system control.
• High Accuracy: The reset threshold is factory-trimmed to 1.6V, ensuring precise monitoring without the need for external adjustments.
• Compact SOT23 Packaging: The device comes in a space-saving 5-pin SOT23 package, making it suitable for high-density PCB layouts.

Applications

• Portable/Battery-Powered Devices
• Embedded Systems
• Data Storage Equipment
• Telecommunications
• Industrial Controllers
