MIC803-40D4VC3-TR Voltage Supervisor from Microchip Technology

The MIC803-40D4VC3-TR is a highly precise voltage supervisor designed to maintain system integrity by monitoring the power supply voltage in electronic equipment. Manufactured by Microchip Technology, a leading provider of microcontroller, mixed-signal, analog, and Flash-IP solutions, this device is an essential component for a wide range of applications, including computers, controllers, and portable electronic devices.

This voltage supervisor is particularly notable for its tight reset threshold of 4.0V, which ensures reliable operation through various power conditions. It features an active-low, open-drain reset output, which remains asserted for a minimum of 140ms after VCC has risen above the designated threshold level. This timing guarantees that the system has adequate time to stabilize before the processor starts up, thus preventing any malfunction due to insufficient power.

The MIC803-40D4VC3-TR comes in a compact SOT-23 package, which is ideal for space-constrained applications. The small footprint of the device allows for efficient use of board space without compromising performance. The part number suffix "TR" indicates that this component is provided in tape and reel packaging, which is suitable for automated assembly processes, making it a convenient choice for high-volume production.

Key features of the MIC803-40D4VC3-TR include:

• Supply voltage monitoring at 4.0V threshold
• Open-drain reset output
• Minimum 140ms reset timeout period
• Low power consumption
• Wide operating voltage range
• Industrial temperature range
• SOT-23 packaging for compact designs

With its precision monitoring and robust feature set, the MIC803-40D4VC3-TR is an excellent choice for designers looking to enhance system reliability and prevent data corruption due to unexpected power dips or outages. Its combination of small size, high accuracy, and ease of integration makes it a versatile solution for maintaining the health and stability of a wide array of electronic systems.
