The TPS22950x is a small, single channel load switch with robust protection against fault cases with adjustable 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 pulldown is used to keep the ON pin from floating until system sequencing is complete. After the pin is deliberately driven high (>VIH), the smart pulldown is disconnected to prevent unnecessary power loss. The TPS22950/C responds to overcurrent events with auto-retry behavior, while the TPS22950L uses a debounce time and latch off behavior. TPS22950x is available in a standard WCSP package and leaded SOT package characterized for operation over an ambient temperature range of –40°C to 125°C.
