Product Overview: MAX6309UK29D3+T by Maxim Integrated

The MAX6309UK29D3+T is a precision, low-power, microprocessor (µP) supervisory circuit designed by Maxim Integrated to monitor power supplies in digital systems. It provides excellent circuit reliability and low cost by eliminating external components and adjustments when used in systems that require voltage monitoring. This supervisory circuit is ideal for use in a wide range of applications, including portable/battery-powered equipment, computers, controllers, and intelligent instruments.

Key Features:

• Voltage Monitoring: This device is tailored to monitor a 2.93V power supply, ensuring that the system voltage does not fall below a minimum threshold, which could lead to system malfunctions.
• Reset Output: The MAX6309UK29D3+T provides an active-low reset signal. It guarantees a valid reset output down to V_CC = 1V. The reset signal remains asserted for a minimum of 140ms after V_CC has risen above the reset threshold, ensuring the system has enough time to stabilize.
• Low Power Consumption: With its low supply current of 5µA (typical), this device is highly suitable for power-sensitive applications.
• High Accuracy: The reset threshold is accurate to ±1.5%, providing a reliable monitor for systems that require precise voltage thresholds.
• Temperature Range: The device operates over an extended temperature range of -40°C to +125°C, making it versatile for various environmental conditions.
• Compact Packaging: The MAX6309UK29D3+T comes in a small, 5-pin SOT23 package, which minimizes the space required on the PCB.
• Immune to Short V_CC Transients: The device includes a built-in time delay, which helps to filter out short-duration voltage dips and prevents false triggering.

Applications:

• Portable/Battery-Powered Devices
• Embedded Systems
• Computers and Servers
• Data Storage Systems
• Medical and Industrial Equipment

The MAX6309UK29D3+T supervisory circuit is a reliable and cost-effective solution for systems that require constant monitoring of the power supply voltage. Its precision and low-power operation make it an excellent choice for maintaining the integrity of digital systems.
