Working Principles

The MIC2591B-2BTQ-TR operates by receiving an enable signal (EN) to activate the power distribution switch. When enabled, it allows the input voltage (IN) to pass through to the output (OUT) with minimal voltage drop. The device continuously monitors the current flowing through it and activates the overcurrent protection (OC) if the current exceeds the set threshold. In case of excessive temperature, the thermal shutdown mechanism is triggered, disabling the output until the temperature returns to a safe level.
