The MAX6740XKSHD3+T is a compact, highly reliable 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 systems with a 3V to 3.6V power supply voltage.

Key Features

• Precision Monitoring: This device features a precision factory-set V<sub>CC reset threshold and offers a ±2.5% reset threshold accuracy over the entire temperature range.
• Low Power Consumption: Designed for power-sensitive applications, the MAX6740XKSHD3+T consumes a low quiescent current of only 5.5µA, making it ideal for battery-operated and portable devices.
• Manual Reset Input: The inclusion of a manual reset input provides a direct way to initiate a system reset, allowing for enhanced control over system functions.
• Watchdog Timer: An integrated watchdog timer improves system reliability by monitoring system operation and initiating a system reset if the software fails to provide a periodic watchdog signal.
• Power-On Reset: The device generates a reset signal on power-up, which ensures that the µP starts in a known state every time the power is applied.

Applications

The MAX6740XKSHD3+T is suitable for a wide range of applications where reliable system operation is critical. These include portable/battery-powered equipment, computers and controllers, embedded controllers, and industrial systems.

Package and Temperature Range

Packaged in a small SOT23-5, the MAX6740XKSHD3+T operates over an extended industrial temperature range of -40°C to +85°C. Its compact size and temperature resilience make it a versatile choice for space-constrained and harsh environment applications.
