Working Principles

The TPS2022DRG4 operates as a high-side power switch. When the enable pin (EN) is activated, the switch connects the input voltage (IN) to the output (OUT), allowing power to flow to the load. The device continuously monitors the current flowing through the switch and compares it to the set current limit. If the current exceeds the limit, the switch is turned off to protect the circuit from damage. Additionally, the TPS2022DRG4 incorporates thermal protection, which disables the switch if the temperature rises above a safe threshold.
