Maxim Integrated MAX6466XR16-T Voltage Monitor

The MAX6466XR16-T is a precision microprocessor (µP) supervisory circuit designed by Maxim Integrated to monitor single-system voltages. This highly compact device is an essential component for systems that require a reliable and accurate monitoring solution to ensure proper operation and to protect against damaging voltage conditions. It is particularly suitable for portable and space-constrained applications due to its small size.

This voltage monitor comes in a tiny SC70/5 package and is engineered to maintain system integrity by monitoring the supply voltage (VCC) and asserting a reset signal whenever VCC drops below the factory-set reset threshold. The reset output remains asserted for a preset timeout period after VCC has risen above the reset threshold, ensuring the system has adequate time to stabilize.

The MAX6466XR16-T features a fixed reset threshold voltage of 1.6V, tailored for low-voltage applications. The device is optimized for low-power consumption, drawing a quiescent current of only 5.5 µA, which is beneficial for battery-powered devices where power efficiency is crucial.

Key features of the MAX6466XR16-T include:

• Factory-Set Reset Thresholds (1.575V to 5.0V in approximately 100mV increments)
• Low 5.5 µA Supply Current
• Guaranteed Reset Valid to VCC = 1.0V
• 140ms (min) Reset Timeout Period
• Immune to Short VCC Transients
• SC70/5 Package for Space-Constrained Applications
• Operating Temperature Range: -40°C to +125°C

Thanks to its robust design, the MAX6466XR16-T ensures that microprocessors and other critical components are protected from unpredictable conditions such as brown-out events. It is an ideal choice for a variety of applications, including portable/battery-powered equipment, computers, controllers, intelligent instruments, and critical µP and µC power monitoring.

Overall, the MAX6466XR16-T from Maxim Integrated is a reliable and efficient solution for voltage monitoring, offering precision, low power consumption, and a small form factor, making it a top choice for designers looking to enhance the safety and performance of their systems.
