Maxim Integrated Product Overview: MAX6734KASYD3-T

The MAX6734KASYD3-T is a highly reliable, 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 and battery control functions.

This supervisory circuit ensures that the µP and other critical system components operate with a stable and accurate supply voltage. It achieves this by providing a reset signal to the µP during power-up, power-down, and brownout conditions. The reset signal remains asserted until the supply voltage reaches the reset threshold level and maintains this level for a specified period, ensuring a proper system restart and preventing code execution errors.

The MAX6734KASYD3-T features an adjustable reset threshold voltage that allows designers to tailor the reset threshold to their specific requirements. This flexibility is essential for a wide range of applications, including portable devices, computers, controllers, and intelligent instruments where precise monitoring is critical.

Additionally, this device offers a manual reset input, which provides a hardware override of the reset output. This feature allows for a system reset without the need to cycle the power, which can be particularly useful during system maintenance or debugging procedures.

Key features of the MAX6734KASYD3-T include:

• Low supply current, which is ideal for battery-operated equipment
• Factory-trimmed reset threshold for high accuracy
• Manual reset input for system-level control
• Immunity to short VCC transients
• Capability to assert reset for a minimum of 140ms (typical) at power-up, which is essential for proper system initialization

Offered in a compact SOT-23 package, the MAX6734KASYD3-T is designed for space-constrained applications. Its wide operating temperature range ensures reliable performance in diverse environments. By choosing the MAX6734KASYD3-T for your design, you are selecting a product from Maxim Integrated, a company known for its high-quality, innovative integrated circuits that solve complex design challenges.
