The Texas Instruments TPS22945DCKR is a load switch IC in a compact SC-70-5 package. It is designed for power distribution applications, offering a wide input voltage range from 1.62V to 5.5V.
Key electrical specifications include a maximum output current of 100mA and a typical on-resistance of 400mΩ at 5.5V input. The device features a fixed current limit, thermal shutdown, and undervoltage lockout (UVLO) for protection. It also includes auto-restart functionality and fault blanking.
The TPS22945DCKR has a shutdown current of less than 1µA and a quiescent current of 40µA, making it suitable for power-sensitive applications. The control input is compatible with 1.8V logic thresholds. The operating temperature range is -40°C to 85°C.
This load switch is mounted using surface mount technology and comes in a 5-TSSOP, SC-70-5, or SOT-353 package. Its small footprint, measuring 4.2 mm² (2 mm × 2.1 mm), makes it ideal for space-constrained designs.
