Maxim Integrated MAX6474US22D3 Voltage Reference IC

The MAX6474US22D3 is a precision, low-dropout microprocessor (µP) reset circuit with a fixed voltage reference from Maxim Integrated. This compact device is engineered to monitor power supplies in µP and digital systems, providing a highly accurate, low-power voltage monitoring solution. It is particularly suitable for portable and battery-powered applications due to its small size and low power consumption.

With a preset voltage threshold of 2.2V, the MAX6474US22D3 ensures that systems operate within their specified voltage ranges, protecting against undervoltage conditions that could lead to system instability or damage. The device features a ±1.5% reset threshold accuracy over the entire operating temperature range of -40°C to +125°C, making it reliable for use in environments subject to temperature variations.

The MAX6474US22D3 offers a manual reset input, which provides a flexible way to initiate a system reset. This feature can be used to trigger a reset from an external event or user input, adding an additional layer of control and security to system operations. The reset output is guaranteed to be in the correct state for VCC down to 1V, ensuring the device will function correctly even under low power conditions.

Designed in a compact SOT-23 package, the MAX6474US22D3 minimizes the footprint on printed circuit boards, an essential factor for space-constrained designs. Its low supply current of 5.5µA (typical) is another advantage for power-sensitive applications, allowing for longer battery life and reduced power costs.

Overall, the MAX6474US22D3 from Maxim Integrated is an excellent choice for designers looking for a reliable and efficient voltage reference IC that can provide accurate monitoring and reset functions in their digital systems. Its precision, low power consumption, and small form factor make it a versatile component for a wide range of applications.
