Frequently Asked Questions

What is the maximum current the TPS2020DRG4 can deliver and how is overcurrent protection handled?

TPS2020DRG4 provides a peak current limit of 300mA with an output current maximum of 200mA continuous, using integrated current-sense circuitry to latch off and protect both the host and USB peripheral from sustained overcurrent faults.

For a USB hub design, how does TPS2020DRG4 help enforce per-port power budgets?

Each TPS2020DRG4 controls one USB port's 5V VBUS rail with a 300mA current limit, allowing a hub controller to enable or disable ports individually via the active-low enable pin, preventing a single faulted device from collapsing the shared 5.5V supply.

Which built-in protection features does TPS2020DRG4 include to survive harsh USB hot-plug events?

TPS2020DRG4 integrates transient protection, overcurrent limiting at 300mA, thermal shutdown, and undervoltage lockout, ensuring the 8-Pin SOIC device automatically recovers or latches off safely during hot-plug inrush and fault conditions.
