5.5V, 3.2A, 34mΩ load switch with adjustable current limit

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.
