The MAX6348UR45+T from Maxim Integrated is a highly reliable, low-power microprocessor (µP) supervisory circuit designed 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 with a 4.5V power supply voltage.

Key Features

• Precision Monitoring: This device features a precision factory-set V<sub>CC reset threshold at 4.5V, ensuring that the system microprocessor is reset to a known state during power-up, power-down, or brownout conditions.
• Low Power Consumption: With low supply current requirements, the MAX6348UR45+T is ideal for portable and battery-powered applications, helping to extend the life of the product's battery.
• Manual Reset Input: An additional manual reset input is provided, allowing for a reset to be triggered with an external push-button or logic signal for increased system control and flexibility.
• Power Supply Transient Immunity: The device is designed to be immune to short duration transients on the V<sub>CC line, which helps to avoid unnecessary system resets and increases overall system robustness.
• Compact Packaging: Offered in a compact SOT-23 package, the MAX6348UR45+T saves valuable board space, which is essential for space-constrained applications.

Applications

The MAX6348UR45+T is suitable for a broad range of applications where precise monitoring of the system power supply is critical. It is commonly used in:

• Computers and Controllers
• Portable/Battery-Powered Equipment
• Intelligent Instruments
• Embedded Systems
• Industrial Controllers

Technical Specifications

With an operating temperature range of -40°C to +85°C, the MAX6348UR45+T can reliably function in diverse environments. The device also features an active-low reset output, which remains asserted for a minimum of 140ms after V<sub>CC has risen above the reset threshold, ensuring the µP has adequate time to stabilize.

For engineers and designers looking for a reliable power monitoring solution, the MAX6348UR45+T from Maxim Integrated is an excellent choice that combines performance, precision, and compact packaging.
