Microchip Technology MIC384-1BMM Voltage Supervisor

The MIC384-1BMM from Microchip Technology is a versatile, adjustable voltage supervisor designed to monitor power supplies in microprocessor systems. It provides a cost-effective solution for systems that require voltage supervision to ensure reliable operation. The device is housed in a compact 8-pin MSOP package, making it suitable for space-constrained applications.

This voltage supervisor is capable of monitoring under-voltage conditions on up to four power rails that are critical to digital system performance. It features an adjustable threshold voltage that allows for precise monitoring of power supplies as low as 0.62V. This flexibility ensures compatibility with a wide range of microprocessors and digital systems.

The MIC384-1BMM offers a manual reset input, which provides an external override to initiate a system reset. This feature is particularly useful for system debugging and recovery. Additionally, the device has an active-low reset output, which remains asserted until the monitored voltage rises above the configured threshold and the internal timer expires, ensuring the system has stabilized before allowing it to resume operation.

With a low supply current of only 15µA, the MIC384-1BMM is an energy-efficient solution that minimizes power consumption in battery-powered devices. It also supports a wide operating temperature range from -40°C to +85°C, making it suitable for industrial and automotive applications where extreme conditions may be encountered.

Key features of the MIC384-1BMM include:

• Adjustable voltage threshold for precise monitoring
• Monitor up to four power rails simultaneously
• Manual reset input for system override and recovery
• Active-low reset output with internal timer for system stability
• Low supply current for energy efficiency
• Wide operating temperature range for harsh environments
• Compact 8-pin MSOP package for space-saving designs

In summary, the MIC384-1BMM from Microchip Technology is a reliable and versatile voltage supervisor suitable for a wide range of applications, from consumer electronics to automotive systems. Its adjustable threshold and low power consumption make it an ideal choice for designers looking to enhance system reliability without compromising on performance or space.
