Maxim Integrated MAX6719UTVHD3-T Microprocessor Supervisory Circuit

The Maxim Integrated MAX6719UTVHD3-T is a highly reliable microprocessor (µP) supervisory circuit designed to maintain system integrity in the face of power fluctuations and other conditions that can compromise the performance and stability of electronic systems. This tiny, low-power device is ideal for monitoring voltages in portable equipment, where space is at a premium and battery life is critical.

This supervisory circuit is adept at monitoring the system voltage and asserting a reset if it detects that the voltage has dropped below a predetermined threshold. The reset function ensures that the µP and other critical system components are held in a reset state until stable system voltage is restored, preventing any erratic system behavior that could arise from low-voltage conditions.

The MAX6719UTVHD3-T features a manual reset input, which provides a hardware override of the reset output, allowing for a system reset without the need for cycling the power. This is particularly useful for system maintenance or software upgrades, where a manual reset can be initiated by a user or a service technician.

With its wide operating voltage range and low supply current, the MAX6719UTVHD3-T is versatile enough to be used in a variety of applications, including portable devices, computers, controllers, and intelligent instruments. Its small SOT23 package makes it an excellent choice for space-constrained applications, while still providing the robust functionality needed to ensure system reliability.

Key features of the MAX6719UTVHD3-T include:

• Compact SOT23 packaging
• Low supply current, ideal for battery-operated devices
• Wide voltage monitoring range to accommodate various system requirements
• Manual reset input for system-level control
• Guaranteed reset valid to VCC = 1V

Overall, the Maxim Integrated MAX6719UTVHD3-T provides designers with a compact, power-efficient solution for voltage monitoring and system reset management, ensuring that electronic systems remain operational and reliable under a broad range of conditions.
