The TPS65988DJRSHR is a dedicated USB Type-C controller PMIC from Texas Instruments, built to manage power delivery and CC (configuration channel) negotiation on a Type-C port. Its supply range of 3.14V to 3.45V means it expects a tightly regulated 3.3V rail — a ±5% tolerance. If your board's 3.3V bus drifts below 3.14V during a transient, the controller drops out; plan the local LDO or buck with enough headroom to stay inside that window. The part draws 8 mA typical supply current, which keeps self-heating negligible in the 56-VQFN (7x7) package. That low Iq also matters for always-on ports where the controller must listen for attach/detach without draining the standby rail.
Commercial temperature grade — indoor deployment only
The –10°C to 75°C operating range is a commercial-grade window. This part is suited for office equipment, consumer docks, and indoor USB hubs. If your application sees an engine bay, outdoor enclosure, or factory floor, the –10°C lower limit is a hard stop — look for an industrial-grade Type-C controller with a –40°C rating.
Texas Instruments has not issued a PCN or end-of-life notice for this order code.
56-VQFN package — footprint and reflow notes
A standard lead-free reflow profile per J-STD-020 works; the MSL level is typically 3 (verify on the reel label).
