Maxim Integrated MAX6746KA31+T Voltage Supervisor

The MAX6746KA31+T is a compact, highly precise voltage supervisor designed to maintain system integrity by monitoring power supplies in digital systems. Manufactured by Maxim Integrated, a leader in analog and mixed-signal products, this device is essential for applications that require reliable operation under varying voltage conditions. It is especially suited for portable, battery-powered devices where power conservation is critical.

This voltage supervisor is part of the MAX6746 series and comes in a small SOT-23 package, making it an ideal choice for space-constrained applications. The MAX6746KA31+T features a factory-set reset threshold voltage of 3.1V, ensuring that systems using 3.3V power supplies can maintain proper function by resetting the system whenever the supply voltage drops below the threshold.

The device boasts a low supply current of only 5.5µA, which is particularly beneficial for battery-operated devices as it helps to extend battery life. Additionally, the MAX6746KA31+T offers a manual reset input, allowing designers to include a user- or processor-controlled reset function. This feature is extremely useful for initiating system reboots or for diagnostic purposes.

With its built-in debounce circuitry, the MAX6746KA31+T ensures that only valid reset signals are processed, preventing false triggering due to transient noise on the line. The device also provides an active-low reset output, which remains asserted for a minimum reset timeout period after V_CC has risen above the reset threshold. This timeout period ensures that the system has sufficient time to stabilize before resuming operation.

Key features of the MAX6746KA31+T include:

• Factory-set reset threshold voltage: 3.1V
• Low supply current: 5.5µA
• Manual reset input
• Debounce circuitry
• Minimum reset timeout period
• Compact SOT-23 package

Overall, the MAX6746KA31+T from Maxim Integrated is an essential component for designers looking to enhance system reliability in their power-sensitive applications. Its precision voltage monitoring and low power consumption make it a smart choice for maintaining system stability and performance.
