TPD3S0x4 Current Limit Switch and D+/D – ESD Protection for USB Host Ports
1 Features 3 Description
The TPD3S0x4s are integrated devices that feature a
1
• Continuous Current Ratings of 0.5 A and 1.5 A
current-limited load switch and a two-channel
• Fixed, Constant Current Limits of 0.85 A and
transient voltage suppressor (TVS) based
2.15 A (Typ)
electrostatic discharge (ESD) protection diode array
• Fast Overcurrent Response – 2 μs
for USB interfaces.
• Integrated Output Discharge
The TPD3S0x4 devices are intended for applications
• Reverse Current Blocking
such as USB where heavy capacitive loads and
short-circuits are likely to be encountered;
• Short-Circuit Protection
TPD3S0x4s provide short-circuit protection and
• Over Temperature Protection With Auto-Restart
overcurrent protection. The TPD3S0x4s limit the
