Maxim Integrated's MAX6803US26D3+T Voltage Monitor

The MAX6803US26D3+T is a compact, low-power microprocessor (µP) supervisory circuit from Maxim Integrated, designed to monitor voltage levels in digital systems and provide a reliable reset signal to the µP whenever necessary. This voltage monitor ensures that your system operates reliably by monitoring the power supply and maintaining system integrity during power-up, brownout conditions, and power-down sequences.

Key Features

• Supply Voltage Monitoring: The MAX6803US26D3+T is designed to monitor a 2.63V threshold, making it suitable for 2.6V-powered systems. Its precision voltage monitoring capability ensures that the device operates within its intended voltage range.
• Low Power Consumption: This device is optimized for low-power operation, consuming only 1.2µA (typical) of supply current. This feature makes it ideal for battery-powered and portable applications where power efficiency is critical.
• Reset Signal: It provides a reset output upon detecting an out-of-tolerance power supply, asserting a reset signal for a minimum of 140ms after VCC has risen above the reset threshold. This reset signal ensures that the µP starts in a known state.
• Compact SOT23 Packaging: The MAX6803US26D3+T comes in a tiny SOT23-3 package, which is excellent for space-constrained applications.
• Temperature Range: It operates over an extended temperature range of -40°C to +125°C, accommodating a wide variety of environmental conditions.
