What are the key features of TPS2086DRG4?
- Quad-channel power distribution with 500 mA continuous and 1 A peak current limit per output channel
- Integrated over-current, thermal shutdown, transient, and under-voltage protection for robust load management
- 4-bit buffer/inverter driver interface for direct logic-level control of each power channel independently
What is TPS2086DRG4 used for?
The TPS2086DRG4 is ideal for USB hubs, set-top boxes, and industrial automation controllers that must independently switch and protect multiple power rails from a single 5 V or 3.3 V bus. Its four integrated current-limited channels replace discrete FET-plus-fuse solutions, reducing board area and improving fault isolation in multi-load power distribution systems housed in 16-pin SOIC packages.

Frequently Asked Questions
How much current can each channel of the TPS2086DRG4 supply before the current limit activates?
Each of the four channels in the TPS2086DRG4 has a 500 mA continuous current rating and a 1 A peak current limit. When load current exceeds the 1 A threshold the device enters current-limiting mode rather than hard shutting down, allowing the system to recover gracefully once the overload condition is removed.
Which built-in protections does the TPS2086DRG4 include and how do they help in industrial designs?
The TPS2086DRG4 integrates four protection mechanisms: over-current limiting at 1 A per channel, thermal shutdown to prevent damage from sustained faults, transient protection for voltage spikes on the power rails, and under-voltage lockout to prevent operation below a safe supply threshold. Together these features eliminate the need for external fuses or TVS diodes on each of the 4 output channels.
Can the TPS2086DRG4 control each power channel independently in a USB hub design?
Yes, all 4 channels have independent enable inputs compatible with standard logic levels, so a host microcontroller can switch each USB port power rail on or off individually. This supports per-port current monitoring and fault management in USB hubs delivering up to 500 mA per port at 5 V.
