What are the key features of TPS2022DRG4?
- 1 A continuous output with 1.5 A peak current limit and built-in overcurrent, thermal, and undervoltage lockout protection
- Single-channel source-driver architecture enabling controlled power sequencing and hot-swap switching in embedded systems
- 8-pin SOIC-8 (MS-012AA) package with 1.27 mm pitch for compact SMD power path designs on 2-layer PCBs
- Integrated protection stack eliminates external fuses and crowbar circuits, simplifying BOM and reducing power distribution board area
What is TPS2022DRG4 used for?
TPS2022DRG4 is designed for USB port power control, PC peripheral bus switching, and portable consumer electronics where a controlled, protected 5 V or 3.3 V power rail must be enabled and disabled under software or hardware control. The built-in overcurrent (1 A continuous, 1.5 A peak limit) and thermal shutdown protect downstream loads during fault conditions without requiring external fuses or thermistors. Its SOIC-8 footprint integrates cleanly into motherboard and hub designs managing multiple switched power domains.

Frequently Asked Questions
What maximum continuous and peak current can TPS2022DRG4 deliver to a downstream load?
TPS2022DRG4 supports 1 A continuous output current with a peak current limit of 1.5 A, providing a safety margin for inrush events during capacitive load charging or motor startup transients. If the load exceeds 1.5 A, the integrated overcurrent protection engages within microseconds, preventing damage to the switch and downstream circuitry.
Which protection mechanisms are built into TPS2022DRG4, and what discrete components do they replace?
TPS2022DRG4 integrates overcurrent limiting at 1.5 A, thermal shutdown triggered above approximately 150 °C junction temperature, and undervoltage lockout to prevent operation below the valid input voltage threshold. These 3 protection functions replace external polyfuses, NTC thermistors, and voltage supervisor ICs, reducing BOM part count by 3 to 5 components per protected rail.
Can TPS2022DRG4 control a USB downstream port supplying 500 mA to a connected device?
Yes, TPS2022DRG4 handles the standard USB 2.0 bus-powered limit of 500 mA with substantial headroom up to its 1 A continuous rating, leaving 500 mA of margin for inrush spikes. The integrated undervoltage lockout ensures the 5 V VBUS rail is valid before enabling the port, preventing enumeration errors on embedded USB hubs and host controllers.
How does the TPS2022DRG4 SOIC-8 package simplify layout compared to a discrete P-channel MOSFET plus gate driver approach?
Replacing a discrete P-channel MOSFET (typically SO-8 or SOT-23-3) plus a gate driver IC (SOT-23-5) plus 3 to 5 passive components with a single TPS2022DRG4 SOIC-8 reduces the power switch circuit from roughly 80 mm² to under 30 mm² while also eliminating the need to calculate gate resistor values and snubber networks for a 1 A switching application.
