Microchip Technology MIC841LBC5-TR Voltage Supervisor

The MIC841LBC5-TR from Microchip Technology is a high-precision voltage supervisor designed to monitor power supplies in digital systems. This tiny but robust component ensures that your microprocessors, microcontrollers, and other digital systems maintain stable operation by resetting these systems in the event of a power failure or brown-out condition. Its primary function is to safeguard your electronic devices from unpredictable power supply fluctuations that could potentially lead to data corruption or hardware damage.

The MIC841LBC5-TR comes in a compact, 5-pin SC-70/SOT-323 package, which makes it ideal for space-constrained applications. Despite its small size, it boasts a high threshold accuracy of ±1.5%, which is crucial for systems that require precise voltage monitoring. The device operates over a voltage range of 1.0V to 5.5V, providing versatility for different power requirements.

One of the key features of the MIC841LBC5-TR is its programmable delay time. This allows designers to set a specific time delay before the reset signal is issued, ensuring that the system has adequate time to stabilize before resuming operation. This programmable delay is achieved through an external capacitor, giving engineers the flexibility to tailor the supervisor's response to the specific needs of their application.

Moreover, the MIC841LBC5-TR offers both active-high and active-low reset outputs, further enhancing its adaptability to various system designs. The device also includes a manual reset input, which provides a means to manually trigger a reset when required.

In terms of power consumption, the MIC841LBC5-TR is highly efficient, with a typical supply current of only 3.8 µA. This low power usage makes it an excellent choice for battery-powered devices where energy efficiency is paramount. Additionally, the device is characterized for operation from -40°C to +85°C, ensuring reliable performance across a wide range of environmental conditions.

Overall, the MIC841LBC5-TR voltage supervisor from Microchip Technology is a highly reliable and versatile component that offers precise voltage monitoring, low power consumption, and a compact form factor, making it an essential part of any power-sensitive digital system design.
