Product details

80 mOhm high-side switch for USB and general-purpose power rails

Fixed current-limiting, over-temperature, and UVLO protections are integrated on-chip.

On/Off control with status flag — what the logic interface expects

The TPS2051AD uses a non-inverting On/Off logic input (enable high = switch on) and provides a Status Flag output that asserts low when the switch is in current limit or thermal shutdown. The 1:1 input-to-output ratio means one enable pin controls one output channel, so no address decoding or daisy-chaining is needed.
