The MAX6838XSD0+TGC1 is a highly reliable, low-power microprocessor (µP) supervisory circuit designed and manufactured by Maxim Integrated. This device is engineered to maintain system integrity by monitoring the power supply voltage in digital systems. It is particularly suitable for battery-powered equipment due to its low power consumption and small footprint.

Featuring a precision factory-set voltage threshold, the MAX6838XSD0+TGC1 ensures that the µP is held in reset until the system voltage has stabilized at the valid level for reliable system operation. This is critical for preventing malfunctions during power-up, power-down, or brown-out conditions.

The reset output from the MAX6838XSD0+TGC1 is guaranteed to be in the correct state for VCC down to 1.0V, which allows for a greater range of safe operation for the connected microprocessor. The reset signal is maintained for a minimum of 140ms after VCC rises above the reset threshold, providing ample time for the system to stabilize.

This supervisory circuit is available in a compact, 4-pin SC70 package, making it an ideal choice for space-constrained applications. The MAX6838XSD0+TGC1 is also characterized for operation over a wide temperature range, from -40°C to +125°C, ensuring reliable performance in harsh environments.

Key features of the MAX6838XSD0+TGC1 include its ability to significantly improve system reliability and accuracy with a low supply current of 1.5µA (typical) and a factory-trimmed reset threshold. The device also boasts a low threshold voltage of 2.93V, which is suitable for a variety of low voltage applications.

Maxim Integrated's commitment to quality means that the MAX6838XSD0+TGC1, like all their products, is designed with the highest standards of performance and reliability in mind. This supervisory circuit is an essential component for designers looking to enhance the operational stability and robustness of their digital systems.
