Analog Devices Inc. ADM811-3TART-REEL7 Voltage Supervisor IC

The ADM811-3TART-REEL7 is a robust voltage supervisor integrated circuit (IC) designed and manufactured by Analog Devices Inc., a leader in high-performance semiconductors. This particular device is tailored to monitor power supplies in digital systems and provide a significant level of reliability required for modern electronic applications.

The ADM811-3TART-REEL7 is part of the ADM811 series, offering an impressive feature set that includes a reset output during power-up, power-down, and brownout conditions. The reset output remains operational with VCC as low as 1.2V. This IC is particularly suitable for portable devices due to its low power consumption and small form factor.

This voltage supervisor operates with a nominal threshold voltage of 3.08V, which is ideal for 3.3V power supply systems. It is designed to maintain system integrity by asserting a reset signal whenever the VCC falls below the minimum voltage threshold, ensuring that the microprocessor or digital system resets cleanly during power-up, power-down, or in the event of an undesired brownout condition.

The ADM811-3TART-REEL7 comes in a convenient surface-mount SOT-143 package and is available on a 7-inch reel, making it suitable for automated manufacturing processes. The packaging is designed for optimal space-saving on PCBs, which is critical in today's compact electronic devices.

Key features of the ADM811-3TART-REEL7 include:

• Watchdog timer for system reliability enhancement
• Manual reset input for added control flexibility
• Low supply current, ideal for battery-powered equipment
• Guaranteed reset output down to VCC = 1.2V
• Power supply transient immunity

This voltage supervisor IC is an excellent choice for managing power systems in a wide array of applications, including computers, controllers, intelligent instruments, and portable consumer electronics. Its reliability and precision make the ADM811-3TART-REEL7 an essential component for any design engineer looking to enhance system stability and performance.
