Product Overview: MAX6468XS29D3+T from Maxim Integrated

The MAX6468XS29D3+T is a highly reliable, low-power voltage supervisory IC produced by Maxim Integrated, a leader in analog and mixed-signal products. This microprocessor (µP) supervisory circuit is designed to monitor power supplies in digital systems, ensuring that the system's microprocessor is reset to a known state during power-up, power-down, or brown-out conditions.

Operating over a wide voltage range, the MAX6468XS29D3+T provides excellent circuit reliability and low cost by eliminating external components and adjustments when used in battery-powered equipment, computers, controllers, and intelligent instruments.

Key Features:

• Voltage Monitoring: This device features a preset factory-trimmed threshold voltage of 2.93V, which is ideal for 3.3V-powered systems.
• Low Power Consumption: With its low supply current of only 1.6µA, the MAX6468XS29D3+T is perfect for power-sensitive applications.
• Reset Output Stage: It offers an active-low, push-pull reset output, which remains asserted for a minimum of 140ms after V_CC has risen above the reset threshold, ensuring a proper system reset.
• High Accuracy: The reset threshold accuracy is maintained at ±1.5% over temperature, voltage, and time, providing a reliable reset operation under varying conditions.
• Temperature Range: The device is operational over an extended industrial temperature range of -40°C to +125°C, which allows for deployment in harsh environments.
