Additional Details

The MIC6315-30D2UTR features a fixed threshold voltage of 3.0V, which is suitable for monitoring 3.3V systems. The active-low reset output asserts a reset signal when the monitored voltage falls below the threshold. The open-drain output allows for flexible interfacing with different logic levels. The manual reset input enables external reset triggering. The device operates over a wide temperature range and is available in a small SOT23-5 package. The low supply current minimizes power consumption. The precise voltage monitoring capability of the MIC6315 ensures accurate and reliable reset generation, preventing system malfunctions.
