Texas Instruments TPS2021DG4 is a single-channel, N-channel high-side power distribution switch designed for general-purpose applications. This device features a 1:1 input-to-output ratio and can deliver a continuous output current of up to 600mA. The TPS2021DG4 integrates fixed current limiting, over-temperature protection, and undervoltage lockout (UVLO) for robust fault management. A status flag provides output fault indication. The switch is controlled via an ON/OFF interface with an inverting input type. With a low ON-resistance of 33mOhm (typical), it minimizes voltage drop. This component is suitable for surface mounting in an 8-SOIC package and operates across a temperature range of -40°C to 125°C. It finds application in various industrial and consumer electronics, including power management systems and portable devices.
