MIC803-26D3VM3-TR Voltage Supervisor from Microchip Technology

The MIC803-26D3VM3-TR is a high-quality voltage supervisor device designed and manufactured by Microchip Technology, a leader in the semiconductor industry. This precision voltage supervisor is engineered to monitor the voltage levels in digital systems and ensure that the system operates reliably within its voltage thresholds. It is an essential component for applications where voltage monitoring and system reliability are critical.

This tiny but robust component comes in a 3-Pin SOT-23 package, making it ideal for space-constrained applications. The MIC803-26D3VM3-TR operates with a nominal threshold voltage of 2.63V, which makes it suitable for supervising 2.5V power supplies and other low-voltage applications. The device features an active-low reset output, which remains asserted for a minimum of 140ms after VCC has risen above the designated reset threshold level, providing ample time for the system to stabilize.

One of the key features of the MIC803-26D3VM3-TR is its low supply current, typically only 3.5µA, which helps to minimize power consumption in battery-operated devices. This makes it an excellent choice for portable electronics, where power efficiency is paramount.

The device also offers a high level of precision, with a threshold voltage accuracy of ±2.5% at room temperature and ±3% over the full temperature range of -40°C to +85°C. This precision ensures that systems are reset accurately and operate within safe voltage levels under various environmental conditions.

Another advantage of the MIC803-26D3VM3-TR is its built-in hysteresis, which prevents reset signal chatter and provides a clean reset signal, further enhancing system stability and reliability. Additionally, it is designed to be tolerant to short VCC transients, ensuring that the system does not reset unnecessarily due to brief voltage dips.

In summary, the MIC803-26D3VM3-TR from Microchip Technology is a compact, low-power, and precise voltage supervisor that offers excellent protection for digital systems. Its small footprint, combined with its low power consumption and high accuracy, makes it an essential component for maintaining the integrity of electronic systems across a broad range of applications.
