The Texas Instruments TPS2046A is a high-side power distribution switch featuring two channels, each capable of handling 250 mA of continuous current. Designed for robustness, it incorporates independent thermal and short-circuit protection mechanisms, along with an overcurrent logic output.
This device operates within a voltage range of 2.7V to 5.5V, making it suitable for a variety of power management applications. The switches utilize an 80 mΩ N-channel MOSFET for efficient power delivery. Enable inputs are CMOS- and TTL-compatible, offering flexibility in control.
The TPS2046A is housed in a D package (SOIC) and is intended for surface mount applications. Its design prioritizes protection against common power system faults like heavy capacitive loads and short circuits, limiting output current to a safe level and shutting down the switch in case of excessive temperature rise.
Key features include a typical rise time of 2.5 ms, undervoltage lockout, and low standby supply current. These characteristics make the TPS2046A a reliable choice for power distribution systems requiring multiple protected switches within a single package.
