MIC803-40D3VC3-TR Voltage Supervisor by Microchip Technology

The MIC803-40D3VC3-TR is a high-quality voltage supervisor device designed and manufactured by Microchip Technology, a leading provider of smart, connected, and secure embedded control solutions. This compact and efficient component is a critical element in enhancing system reliability by monitoring the power supply voltage of digital systems, ensuring that the system operates within its specified voltage range.

With a precision voltage monitoring threshold of 4.0V, the MIC803-40D3VC3-TR is particularly suited for 3.3V systems that require a higher degree of accuracy in power supply monitoring. It is designed to assert a reset signal whenever the VCC voltage drops below the minimum threshold, keeping the reset active until the voltage recovers and maintains stability for a specified period, typically 140ms. This reset delay time ensures that the system has adequate time to stabilize before resuming normal operation, thereby preventing any malfunction due to brief power dips or brownouts.

The device comes in a compact 3-pin SOT-23 package, which is ideal for space-constrained applications. The MIC803-40D3VC3-TR is also characterized for operation over a temperature range of -40°C to +85°C, making it suitable for a wide range of industrial and consumer applications where temperature variation is a concern.

Furthermore, the MIC803-40D3VC3-TR is available in tape and reel packaging, denoted by the suffix "-TR", which facilitates automated assembly processes and is convenient for mass production requirements. This packaging option ensures that the components are delivered in a ready-to-use format for high-speed manufacturing environments.

Microchip Technology's commitment to quality means that the MIC803-40D3VC3-TR voltage supervisor is designed for reliability and performance, making it an excellent choice for designers looking to incorporate a robust power monitoring solution into their systems. Whether used in consumer electronics, automotive applications, or industrial control systems, this voltage supervisor provides a simple yet effective way to enhance system stability and protect against the consequences of undesirable power supply fluctuations.
