Microchip Technology MIC384-2BMM Voltage Supervisor

The MIC384-2BMM from Microchip Technology is a versatile, programmable voltage supervisor designed to monitor up to four system supply voltages. This compact component is an essential device for reliable system operation, ensuring that all system voltages remain within specified thresholds to prevent potential damage from power surges, brownouts, or other types of electrical instability.

Featuring a small 10-pin MSOP (Mini Small Outline Package) footprint, the MIC384-2BMM is ideal for space-constrained applications. It is highly suited for multi-voltage systems where precision monitoring is critical, such as in embedded systems, computers, and telecommunications equipment.

One of the key features of the MIC384-2BMM is its programmability. With an external resistor divider, users can set the threshold for each voltage monitor, allowing for a high degree of customization to match specific system requirements. This flexibility ensures that the device can adapt to a wide range of applications and configurations.

The device offers several other notable features, such as:

• Low supply current, which enhances overall system efficiency and is particularly beneficial for battery-operated devices.
• An adjustable hysteresis setting that prevents false triggering, ensuring stable operation even in noisy environments.
• A manual reset input that allows for a system reset without cycling the power supply.
• An active-low reset output, which remains asserted for a minimum of 140ms after all voltages have stabilized, providing ample time for the system to recover from an out-of-tolerance condition.

The MIC384-2BMM also includes built-in undervoltage lockout (UVLO) and overtemperature shutdown features, which further enhance the protection of the system it monitors. These safeguards ensure that the device is not only monitoring voltages but also actively contributing to the overall stability and longevity of the system.

With its combination of precision, flexibility, and compact design, the MIC384-2BMM voltage supervisor from Microchip Technology is an excellent choice for any designer looking to enhance system reliability and performance.
