Texas Instruments TPS65982DAZBHR

Overview

TPS65982DAZBHR from Texas Instruments is a USB Type-C® and Power Delivery 2.0–certified controller integrating power switching, USB 2.0/DisplayPort multiplexing, and CC-line BMC PHY. It delivers 5 V/3 A sourcing, 5–20 V/3 A bidirectional PD power path control, and supports DisplayPort alternate mode in rugged docking stations and flat-panel monitors.

For engineers reviewing the TPS65982DAZBHR datasheet, TPS65982DAZBHR pinout, TPS65982DAZBHR application, or TPS65982DAZBHR equivalent, key selection factors include USB PD 2.0 certification status, integrated 96-pin NFBGA package with dual I²C ports, 8 configurable GPIOs, VCONN switch, and support for dead-battery operation via VBUS-powered 3.3-V LDO.

Technical Context

The TPS65982DAZBHR implements a full USB PD 2.0 policy engine with Bi-phase Mark Coding (BMC) physical layer, cable orientation detection, and autonomous contract negotiation. Its mixed-signal CC front end advertises 3 A default power role and handles plug detection without host intervention.

It integrates three independent power paths: a 5-V/3-A sourcing switch (50 mΩ), a 5–20 V/3-A bidirectional load switch (95 mΩ), and gate drivers + current sense for external 5–20 V/5-A back-to-back NFETs - all with UL2367 and IEC62368-1 safety certification.

FAQ

Is TPS65982DAZBHR USB PD 3.0 certified?

No, TPS65982DAZBHR is USB PD 2.0 certified only. As stated in its official documentation, PD 2.0 certification was discontinued for new designs after June 2020. The TPS65982DAZBHR cannot be certified to PD 3.0 and lacks support for Programmable Power Supply (PPS) and extended message features required by that standard. For new designs, TI recommends TPS65987DZQZ as the PD 3.0–compliant successor to the TPS65982DAZBHR.

What package type does TPS65982DAZBHR use?

TPS65982DAZBHR uses a 96-pin NFBGA (No-Lead Fine-Pitch Ball Grid Array) package with MicroStar Junior footprint and 6.00 mm × 6.00 mm body size. This package is identical to the ZQZ variant and requires 0.4-mm ball pitch, thermal vias under the exposed pad, and strict adherence to TI's layout guidelines for signal integrity and thermal performance.

Does TPS65982DAZBHR support dead-battery operation?

Yes, TPS65982DAZBHR supports dead-battery operation through its integrated VBUS-powered 3.3-V LDO (LDO_3V3). When VIN_3V3 is absent, the device draws power directly from VBUS to generate LDO_3V3, enabling firmware execution, flash loading, and basic PD negotiation - critical for laptops and docks that must power up with zero battery charge.

Can TPS65982DAZBHR drive external high-current power FETs?

Yes, TPS65982DAZBHR includes dedicated analog gate drivers (HV_GATE1/HV_GATE2) and current sense inputs (SENSEP/SENSEN) to control external back-to-back NFETs in a 5–20 V/5-A bidirectional power path. This capability extends beyond its internal 3-A switches and is validated per UL2367 and IEC62368-1 standards when implemented with appropriate external components.

What alternate modes does TPS65982DAZBHR support?

TPS65982DAZBHR natively supports DisplayPort alternate mode via SBU1/SBU2 and USB 2.0 HS D± routing, and explicitly lists Thunderbolt alternate mode compatibility in its official features. It provides full sideband-use (SBU) detection, AUX channel routing, and HPD signaling through configurable GPIOs (GPIO4/GPIO5), enabling seamless integration into DP-enabled docks and monitors without additional protocol translators.
