Working Principles

The MIC2070-1BQS operates as a high-side load switch by controlling the power distribution between the input (IN) and output (OUT) pins. When the enable (EN) pin is high, the power switch is turned on, allowing current flow from the input to the output. The device continuously monitors the load current and compares it with the set overcurrent protection threshold. If the current exceeds this threshold, the power switch is turned off, providing protection against excessive current. Additionally, the device incorporates thermal shutdown functionality, which triggers when the temperature reaches a critical level, ensuring safe operation.
