Analog Devices Inc. ADM809-5SAKSZ-REEL7

The ADM809-5SAKSZ-REEL7 is a high-performance supervisory circuit designed and manufactured by Analog Devices Inc., an industry leader in the field of high-performance analog, mixed-signal, and digital signal processing integrated circuits. This product is specifically engineered to monitor power supplies in microprocessor and digital systems, providing a significant layer of protection and stability to the overall system.

One of the key features of the ADM809-5SAKSZ-REEL7 is its ability to provide a precise monitoring solution for 5V power supplies. The device holds a microprocessor system in reset until the supply voltage reaches a stable and accurate threshold level. Once the supply voltage exceeds the reset threshold, the ADM809-5SAKSZ-REEL7 keeps the processor in reset for a minimum of 140 ms, ensuring a proper system startup.

This supervisory circuit comes in a compact SOT-23 package, which is ideal for space-constrained applications. It is offered in a tape and reel format under the REEL7 designation, making it suitable for automated assembly processes, thus streamlining the manufacturing and assembly for high-volume production.

The ADM809-5SAKSZ-REEL7 also features a low power consumption, making it an excellent choice for portable and battery-operated equipment. The device's active-low reset output ensures compatibility with a wide range of microprocessors and DSPs, which often require an active-low reset signal.

For added flexibility, the ADM809-5SAKSZ-REEL7 includes a manual reset input. This allows for a reset to be triggered with an external push-button or logic signal, providing an additional layer of control for system designers and operators. The manual reset capability is an essential feature for systems that require user intervention to initiate a system reset.

In summary, the ADM809-5SAKSZ-REEL7 from Analog Devices Inc. is a robust and reliable supervisory circuit that offers precise voltage monitoring, low power consumption, and a small footprint, making it an ideal choice for ensuring the integrity and stability of digital systems.
