The TPS22948 device is a small, single channel load switch with robust protection against fault cases with output current limiting, reverse current blocking, and thermal shutdown.
The switch ON state is controlled by a digital input that is capable of interfacing directly with low-voltage control signals. When power is first applied, a smart pull down is used to keep the ON pin from floating until system sequencing is complete. Once the pin is deliberately driven high (>VIH), the smart pull down will be disconnected to prevent unnecessary power loss. ™
TPS22948 is available in a standard SC-70 package characterized for operation over a temperature range of –40°C to 125°C.

TPS22948EVM — TPS22948 5.5V、0.3A 電流限制負載開關評估模組
The TPS22948 evaluation module (EVM) is an assembled and tested circuit for evaluating the TPS22948 load switches. The TPS22948EVM allows the user to apply different input voltages (1.6 V to 5.5 V) under different loading conditions (0 A to 0.3 A) to the TPS22948 device. Parameters such as the (...)
