Product Overview: MAX6337US16D3+T from Maxim Integrated

The MAX6337US16D3+T is a high-precision, low-power microprocessor (µP) supervisory circuit from Maxim Integrated, designed to monitor power supplies in digital systems. It provides a significant level of system reliability and accuracy required in critical applications, ensuring that the digital system operates within safe voltage levels. This device is particularly well-suited for portable and battery-powered equipment due to its low power consumption and small footprint.

This supervisory circuit features a factory-trimmed reset threshold voltage of 1.6V, which is ideal for monitoring 1.8V power supplies. The reset output is active low and remains asserted for a minimum reset timeout period of 1.6 seconds after V_CC has risen above the reset threshold. This ensures that the µP has sufficient time to initialize and stabilize before the system resumes operation.

The MAX6337US16D3+T is available in a compact, 4-pin SOT-143 package, making it an excellent choice for space-constrained applications. It operates over a wide temperature range of -40°C to +85°C, ensuring reliable performance under varying environmental conditions.

Key Features:

• Factory-trimmed V_CC reset threshold voltage: 1.6V
• Low supply current: 5.5µA (typical), which is ideal for battery-powered applications
• Minimum reset timeout period: 1.6 seconds
• Operating temperature range: -40°C to +85°C
• Compact SOT-143 package
• Immune to short V_CC transients
• No external components required

Applications:

• Portable/Battery-Powered Equipment
• Computers and Controllers
• Embedded Systems
• Data Storage Systems
• Industrial Controls

The MAX6337US16D3+T supervisory circuit is designed to enhance system reliability by providing a robust power-on reset functionality. It ensures that microprocessors and other critical system components are held in reset until the system voltage has stabilized, preventing erratic operation. With its precision monitoring capabilities and low power requirements, the MAX6337US16D3+T is an essential component for designers looking to improve system integrity and extend battery life in their digital applications.
