Maxim Integrated MAX6703TEKA+T Microprocessor Supervisory Circuit

The Maxim Integrated MAX6703TEKA+T is a high-quality 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 system monitoring applications.

This supervisory circuit is particularly adept at ensuring that the µP boots up properly every time. It achieves this by monitoring the power supply voltage and asserting a reset if the supply voltage drops below a predetermined threshold. The reset output remains asserted for a period after the supply voltage rises above the reset threshold, ensuring the µP has adequate time to initialize.

The MAX6703TEKA+T comes in a compact SOT-23 package, making it ideal for space-constrained applications. Its low power consumption is an asset for portable and battery-operated devices. The device operates over a wide voltage range, making it versatile for various applications.

Key features of the MAX6703TEKA+T include:

• Precision monitoring of 3V, 3.3V, and 5V power-supply voltages.
• 140ms min power-on reset pulse width that ensures proper system reset.
• Manual reset input for system-level reset functionality.
• Low power consumption, suitable for battery-powered applications.
• Guaranteed reset valid to V<sub>CC = 1V for low voltage operations.
• Wide operating temperature range, making it suitable for industrial applications.
• Compact SOT-23 packaging for space-saving installations.

The MAX6703TEKA+T is designed to be a reliable component in any system that requires a watchdog timer or other supervisory functions. Its ability to reset a system automatically in the event of a power fault makes it an invaluable part of ensuring continuous and reliable operation. Whether it's used in computers, controllers, intelligent instruments, or portable devices, the Maxim Integrated MAX6703TEKA+T provides the security and assurance that systems will operate as intended.
