Microchip Technology MIC811JU TR Voltage Supervisor

The MIC811JU TR from Microchip Technology is a highly reliable voltage supervisor device designed to keep microprocessor systems safe by monitoring power supplies in digital systems. This component ensures that your system operates within safe voltage levels, providing a reset signal to the processor whenever necessary.

Equipped with a precision voltage sensor, the MIC811JU TR monitors the supply voltage of a microprocessor or digital system. When the supply voltage drops below a predetermined threshold, the device asserts a reset signal to prevent system errors or data corruption. The reset signal remains asserted until the supply voltage returns to an acceptable level, plus a delay time to ensure system stability.

The device features an active-low reset output, which is guaranteed to be in the correct state for VCC down to 1V. This makes the MIC811JU TR particularly suitable for low voltage operation and ensures compatibility with a wide range of microprocessors and digital systems that require a strict power monitoring regime.

Furthermore, the MIC811JU TR is offered in a compact 4-pin SOT-143 package, making it an ideal choice for space-constrained applications. Its small footprint allows for easy integration into system designs without significantly impacting the overall size of the product.

Key specifications of the MIC811JU TR include:

• Supply voltage monitoring for 3V, 3.3V, and 5V systems
• Low power consumption
• 140 ms (minimum) reset pulse width
• Active-low RESET output
• Accuracy of ±2.5% over temperature
• Immune to short VCC transients
• Operating temperature range from -40°C to +85°C

Whether you're designing a critical system that cannot afford to fail or simply looking to improve the reliability of your digital products, the MIC811JU TR voltage supervisor from Microchip Technology is a dependable solution that offers peace of mind with its robust feature set and proven performance.
