The MAX6800UR29D3+T is a compact, high-precision voltage monitor designed by Maxim Integrated, a company renowned for its innovative and reliable integrated circuits. This device is specifically engineered to safeguard systems against undervoltage conditions, ensuring that electronic equipment operates within its safe voltage thresholds.

With a fixed threshold voltage of 2.93V, the MAX6800UR29D3+T is ideal for monitoring 3.3V power supplies, providing a critical safeguard for microcontrollers and other sensitive digital circuits that require stable voltage levels for optimal performance. The monitor asserts a reset signal when the monitored voltage falls below the threshold, and maintains the reset condition until the voltage recovers to an acceptable level, plus a built-in delay to avoid false triggering due to transient dips.

The device comes in a tiny, 3-pin SOT-23 package, making it suitable for space-constrained applications. The MAX6800UR29D3+T is also characterized by its low power consumption, drawing a quiescent current of only 1.2µA, which is particularly advantageous for battery-powered devices where energy efficiency is paramount.

Key features of the MAX6800UR29D3+T include:

• Fixed 2.93V Threshold Voltage
• Low 1.2µA Supply Current
• Guaranteed Reset Valid to VCC = 1V
• 140ms (min) Reset Timeout Period
• Immunity to Short VCC Transients
• Compact SOT-23 Packaging

Applications for the MAX6800UR29D3+T are diverse and include portable/battery-powered equipment, computers, controllers, intelligent instruments, and any system that requires a reliable undervoltage protection mechanism. The device's temperature range of -40°C to +125°C ensures reliable operation across a wide range of environmental conditions.

With its precision voltage monitoring and low power consumption, the MAX6800UR29D3+T from Maxim Integrated is an excellent choice for designers looking for a simple, effective solution to protect their electronic systems from undervoltage conditions without sacrificing board space or energy efficiency.
