Maxim Integrated MAX6309UK31D3+T Voltage Supervisor IC

The MAX6309UK31D3+T is a highly precise, low-power voltage supervisor IC designed and manufactured by Maxim Integrated. This compact, single-component solution is engineered to monitor power supplies in digital systems, ensuring that the system operates reliably within its voltage thresholds. It is an essential component for a wide range of applications, including microprocessor and microcontroller-based systems, portable and battery-powered equipment, and industrial controllers.

This voltage supervisor IC features a factory-set reset threshold voltage of 3.08V, which is ideal for 3.3V powered systems. The MAX6309UK31D3+T comes in a small, space-saving SOT-23 package, which is perfect for systems where space is at a premium. The device operates over a wide temperature range of -40°C to +125°C, making it suitable for use in harsh environments.

One of the key attributes of the MAX6309UK31D3+T is its low power consumption. With a quiescent current of only 1µA, it helps to extend the battery life in portable applications. The device also offers a manual reset input, which allows the system to be reset manually without the need to cycle the power.

Furthermore, the MAX6309UK31D3+T provides a reset output that remains asserted for a minimum of 140ms after the supply voltage has risen above the reset threshold. This ensures that the system has sufficient time to stabilize before the processor starts operating. The reset output is available in either an active-low push-pull or an active-low open-drain configuration, providing flexibility for different system requirements.

Designed with reliability in mind, the MAX6309UK31D3+T includes additional features such as thermal-shutdown protection and a robust immunity to short voltage transients. This makes the device a dependable choice for critical applications where system stability and data integrity are paramount.

In summary, the MAX6309UK31D3+T from Maxim Integrated is a versatile and reliable voltage supervisor IC that offers precise monitoring, low power consumption, and a compact form factor, making it an excellent choice for a variety of electronic systems.
