Four-channel high-side switching with system flags
The TPS2075DB: Four independent N-channel high-side outputs, each rated 100 mA continuous, cover a typical USB downstream port or peripheral power distribution tree. The 100 mOhm typical Rds(on) keeps the voltage drop below 10 mV at full load per channel, so the 5V bus stays within USB 2.0 tolerance at the far end. On/Off interface with integrated Power Good and Status Flag outputs gives the host controller real-time visibility into each channel's state and fault condition. Over-temperature protection shuts down the switch before junction damage occurs — the part recovers automatically when the die cools.
