MIC803-44D2VC3-TR Voltage Supervisor from Microchip Technology

The MIC803-44D2VC3-TR is a high-quality voltage supervisor device designed and manufactured by the reputable Microchip Technology. This precision voltage monitoring component is ideal for managing power supplies in sophisticated electronic systems, ensuring reliable operation and system stability. It is particularly well-suited for battery-powered devices, microcontrollers, and other applications where power conditions must be carefully controlled.

At the heart of the MIC803 lies its ability to accurately detect under-voltage conditions. The device features a nominal threshold voltage of 4.4V, which makes it suitable for monitoring 5V power supplies and ensuring they remain within acceptable operating limits. When the monitored voltage falls below the 4.4V threshold, the MIC803-44D2VC3-TR asserts a reset signal, which remains active until the voltage recovers to an acceptable level, plus a certain delay time to prevent false triggering.

The MIC803-44D2VC3-TR comes in a compact, 3-pin SOT-23 package, which is ideal for space-constrained applications. Its small footprint allows it to be used in dense PCB layouts without compromising performance. Additionally, this device is characterized for operation over a wide temperature range of -40°C to +85°C, making it suitable for use in harsh environments.

One of the key features of this voltage supervisor is its low supply current, which is particularly beneficial for portable and battery-operated devices where power efficiency is critical. The MIC803-44D2VC3-TR also includes a manual reset input, which provides an additional layer of system control by allowing the user to manually initiate a reset whenever necessary.

As a testament to its reliability, the MIC803-44D2VC3-TR is provided in tape and reel packaging, designated by the '-TR' suffix, which facilitates automated assembly processes and ensures a smooth integration into mass production lines. This packaging option is especially useful for manufacturers who require efficient, high-volume production capabilities.

In summary, the MIC803-44D2VC3-TR from Microchip Technology is a robust and reliable solution for voltage supervision needs in a wide range of electronic applications. Its precision, low power consumption, and small form factor make it an excellent choice for engineers looking to enhance the safety and reliability of their power management systems.
