TPD4S214 (ACTIVE) USB OTG Companion Device With Vbus Overvoltage, Overcurrent Protection, and Four-Channel ESD Clamp

 

Description

The TPD4S214 is a single-chip protection solution for USB On-the-Go (OTG) and other current limited USB applications. This device includes an integrated low RDS(ON) N-channel current limited switch for the OTG current supply to peripheral devices. TPD4S214 offers low capacitance transient voltage suppression (TVS) electrostatic discharge (ESD) clamping diodes for the D+, D–, and ID pins for both USB2.0 and USB3.0 applications. The VBUS pin can handle continuous voltage ranging from –7 V to 30 V. The over voltage lock-out (OVLO) at the VBUS pin ensures that if there is a fault condition at the VBUS line, TPD4S214 is able to isolate it and protect the internal circuitry from damage. Similarly, the under voltage lock out (UVLO) at the VOTG_IN pin ensures that there is no power drain from the internal OTG supply to external VBUS if VOTG_IN droops below a safe operating level. When EN is high, the OTG switch is activated and the FLT pin indicates whether there is a fault condition. The soft start feature waits 16 ms to turn on the OTG switch after all operating conditions are met.
