Maxim Integrated MAX6309UK26D3+T Voltage Supervisor IC

The MAX6309UK26D3+T is a highly precise voltage supervisor IC designed by Maxim Integrated, a renowned leader in the development of integrated circuits. This compact, low-power component is engineered to maintain system integrity by monitoring the power supply voltage in digital systems. It is particularly suitable for applications that require a high degree of reliability and accuracy, such as portable devices, embedded systems, and industrial equipment.

The MAX6309UK26D3+T is characterized by its preset voltage threshold of 2.63V, which is ideal for supervising 2.5V power supplies. Upon detecting a voltage drop below the threshold, the device asserts a reset signal, ensuring that the microprocessor or digital system resets cleanly. The reset output remains asserted for a minimum of 140ms after the supply voltage rises above the reset threshold, providing ample time for the system to stabilize.

This voltage supervisor comes in a compact SOT-23 package, making it an excellent choice for space-constrained applications. Its tiny footprint allows designers to incorporate it into systems where board space is at a premium without sacrificing performance or reliability.

Key features of the MAX6309UK26D3+T include:

• Factory-trimmed reset threshold voltage of 2.63V
• Low supply current of 1.2µA, ideal for battery-powered applications
• Guaranteed reset valid to VCC = 1V
• Immunity to short VCC transients
• Push-pull active-low reset output
• Temperature range from -40°C to +125°C

The device's low supply current ensures minimal power consumption, which is crucial for extending battery life in portable devices. Additionally, the MAX6309UK26D3+T's immunity to short-duration voltage transients prevents false triggering, which can lead to unnecessary system resets and potential data loss.

Overall, the MAX6309UK26D3+T from Maxim Integrated is a robust and reliable solution for voltage monitoring and system reset functions. Its precision, low power consumption, and small size make it an excellent choice for designers looking to enhance system reliability without compromising on space or power efficiency.
