• Low power consumption with a typical supply current of 1µA, making it ideal for power-sensitive applications.
• Manual reset input for additional system control.
• Reset timeout of 140ms (min) provides a reliable system reset.
• Compact SOT-23 package suitable for space-constrained applications.
• Temperature range from -40°C to +85°C ensures operation in diverse environmental conditions.
• Immune to short VCC transients, enhancing system stability.

Applications

• Portable/Battery-Powered Equipment
• Notebook Computers
• Embedded Controllers
• Intelligent Instruments
• Automotive Systems

The MAX6366LKA23+T is engineered to assert a reset signal whenever the VCC supply voltage falls below the preset threshold, ensuring the proper operation of the microprocessor by preventing code execution errors during power-up, power-down, and brown-out conditions. The device's reset output remains asserted for a minimum of 140ms after VCC has risen above the reset threshold level, providing the system with adequate time to stabilize.

Its tiny SOT-23 package makes it an excellent choice for portable applications where space is at a premium. Furthermore, the low supply current feature extends battery life, which is critical for portable and wearable technology. With its robust design and Maxim Integrated's reputation for quality, the MAX6366LKA23+T is a trusted component for designers looking to enhance the reliability and performance of their digital systems.
