Product Overview: MIC812MUY-TR by Microchip Technology

The MIC812MUY-TR from Microchip Technology is a highly reliable, compact, and efficient voltage supervisor designed to monitor the power supply voltage of digital systems. It provides a crucial function by asserting a reset signal whenever the monitored voltage falls below a predetermined threshold, ensuring that the system operates within its specified voltage range. This feature helps in preventing system errors and data corruption that can occur due to unexpected power fluctuations or brown-out conditions.

With its small SOT-23 package, the MIC812MUY-TR is ideal for space-constrained applications where board real estate is at a premium. Despite its diminutive size, this voltage supervisor does not compromise on performance, offering a precise monitoring capability with a factory-trimmed threshold voltage. The device is suitable for a wide range of products, including microcontrollers, embedded systems, and portable electronic devices where reliable power management is essential.

The MIC812MUY-TR boasts a low power consumption, making it an excellent choice for battery-operated devices. Its active-low reset output ensures compatibility with most microprocessor and microcontroller systems. The reset signal is maintained for a minimum of 140ms (typical) after the supply voltage has risen above the reset threshold level, providing ample time for the system to stabilize before normal operation resumes.

Key features of the MIC812MUY-TR include:

• Supply voltage monitoring to prevent system instability
• Factory-programmed V<sub>TH for high accuracy
• Low supply current suitable for battery-powered applications
• 140ms minimum reset pulse width
• Operating temperature range from -40°C to +85°C
• Immunity to short V<sub>CC transients

This voltage supervisor from Microchip Technology is an essential component for maintaining the integrity of electronic systems. The MIC812MUY-TR's robust design and reliable performance ensure that it can meet the stringent requirements of modern digital applications, providing designers with a trusted solution for their power monitoring needs.
