Maxim Integrated MAX6803US44D3+T Voltage Detector

The MAX6803US44D3+T from Maxim Integrated is a highly precise, low-power voltage detector designed for monitoring battery, power-supply, and regulated system voltages. This compact device is an essential component for portable devices, microprocessor and microcontroller-based systems, and any application where voltage supervision is critical to protect sensitive electronic components.

Operating with a nominal threshold voltage of 4.4V, the MAX6803US44D3+T provides designers with a reliable solution for systems that require a specific supervisory voltage level. The device is capable of detecting under-voltage conditions, thereby preventing system malfunction due to insufficient power supply.

With its tiny SOT-23 package, the MAX6803US44D3+T is an excellent choice for space-constrained applications. Despite its small size, it offers a robust feature set, including a low quiescent current of only 1.2µA at +25°C, which is ideal for battery-powered devices where energy efficiency is paramount.

One of the key benefits of this voltage detector is its ±2.5% voltage threshold accuracy over the extended temperature range of -40°C to +125°C. This precision ensures reliable operation even under varying environmental conditions, making the MAX6803US44D3+T suitable for automotive and industrial applications as well.

The device also includes a manual reset input, allowing for system reset initiation by external events or user interaction. Additionally, it offers a 140ms (min) reset timeout period, providing enough time for the power supply to stabilize before allowing the system to resume operation.

The MAX6803US44D3+T is available in a lead(Pb)-free, 3-pin SOT-23 package and is fully RoHS compliant. It is part of a family of voltage detectors from Maxim Integrated that offer different voltage thresholds and reset timeout periods, enabling designers to select the perfect match for their specific application requirements.

With its combination of accuracy, low power consumption, and small footprint, the Maxim Integrated MAX6803US44D3+T voltage detector is an excellent choice for ensuring system stability and integrity across a wide range of electronic products.
