Disadvantages: - Limited output current capacity (up to 500mA) - Restricted operating temperature range (-40°C to +85°C)

Working Principles

The MIC2005A-2YM5-TR operates as a power switch by controlling the flow of current between the input and output pins. When the enable pin (EN) is high, the switch is turned on, allowing current to flow from the input pin (IN) to the output pin (OUT). Conversely, when the enable pin is low, the switch is turned off, blocking the current flow.

The IC continuously monitors the current passing through it and activates the overcurrent protection mechanism if the current exceeds a predetermined threshold. Additionally, the thermal protection feature prevents the IC from overheating by shutting off the switch when the temperature rises above a specified limit.
