USB power switch in SOT-23-5
The TPS2001DDBVT: The 72 mOhm typical on-resistance keeps conduction losses low in a compact SOT-23-5 footprint.
Protection suite and output control
Fault protection covers current limiting (fixed), over-temperature shutdown, reverse-current blocking, and under-voltage lockout (UVLO) — the four conditions that typically take out an unprotected USB port. A status flag output signals fault events to the host controller. The switch is enabled by a non-inverting On/Off interface and requires no external Vcc supply rail — the gate drive is self-biased from the load voltage.
Package and temperature grade
The supplier device package is SOT-23-5; the tape-and-reel and cut-tape options are listed for volume and prototype procurement respectively.
