Maxim Integrated MAX6719UTSFD3+T Microprocessor Supervisory Circuit

The Maxim Integrated MAX6719UTSFD3+T is a highly reliable and versatile microprocessor (µP) supervisory circuit designed to monitor power supplies and microprocessor activity 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 processor supervision.

This compact supervisory circuit features a quad voltage monitor with manual reset capability, ensuring that your system operates within safe voltage thresholds. The MAX6719UTSFD3+T is specifically designed to improve the system's reliability by monitoring the power supply voltages and asserting a reset if any monitored supply falls below its programmed threshold. The reset output remains asserted for the reset timeout period after all voltages rise above their respective thresholds, ensuring that the µP is reset properly during power-up, power-down, and brownout conditions.

The device comes in a small, 6-pin SOT23 package, making it suitable for space-constrained applications. It is characterized for the extended temperature range of -40°C to +125°C, which allows it to operate reliably in a wide range of environments and applications. The MAX6719UTSFD3+T is also available in a lead(Pb)-free/RoHS-compliant package, addressing environmental concerns and regulatory requirements.

Key features of the MAX6719UTSFD3+T include:

• Quad voltage monitoring for system reliability
• Manual reset input with debounce
• Low supply current, making it energy efficient
• Guaranteed reset valid to VCC = 1V
• Power supply transient immunity
• No external components required
• Compact 6-pin SOT23 package

Applications for the MAX6719UTSFD3+T are diverse and include:

• Portable/Battery-Powered Equipment
• Computers and Controllers
• Automotive Systems
