Working Principles

The TPS2012DRG4 operates as a high-side power switch, controlling the flow of power from the input to the output. When the enable pin is activated, the internal circuitry allows current to flow from the input to the output. The low on-resistance ensures minimal power loss during this process. The adjustable overcurrent protection threshold safeguards the system by interrupting the power flow when the current exceeds a set limit. Additionally, the thermal shutdown feature protects the IC from overheating, ensuring its longevity.
