TPS65988DDK 概要
A USB Type-C and Power Delivery controller is a specialized power management IC that negotiates voltage, current, and role (source/sink) over the USB Type-C Configuration Channel (CC) lines using the USB PD protocol. Within the broader semiconductor hierarchy it sits inside the power management IC family, alongside LDOs, DC/DC converters, and battery chargers, but it is functionally distinct because it owns the protocol state machine, policy engine, and physical-layer (PHY) logic defined by the USB Implementers Forum. Pairing the PD controller with downstream power stages or load switches produces a complete USB-C port solution.
Key features of the TPS65988DDK include USB PD 3.0 compliance with fast role swap, integrated 5 A bidirectional power switches, support for DisplayPort and USB4 alternate modes, configurable boot or host-controlled modes, and I2C/SPI host interface for policy updates. Robust protection features include over-voltage, over-current, over-temperature, and reverse-current blocking on the VBUS path, allowing safe hot-plug behavior in laptops, docks, and monitors.
Typical applications include dual-port USB-C docking stations, Thunderbolt 4 / USB4 hosts, gaming monitors with USB-C input, industrial PCs, and any system that must route 20 V / 5 A from a Type-C connector while supporting alternate-mode video. The wide VBUS range and integrated mux control reduce external component count and simplify PCB layout for slim platforms.
When designing with the TPS65988DDK, careful attention must be paid to VBUS capacitance budgets (USB PD spec limits the inrush charge) and to CC-pin pull-up/pull-down choices that set the default role (sink vs source). Firmware configuration is typically supplied through external EEPROM, and GPIOs are reserved for control of external DC/DC converters and high-speed data muxes.

主な用途
TPS65988DDK の用途: 6 件s: Dual-Port USB-C Docking Station, Thunderbolt 4 / USB4 Host Implementation, USB-C Monitor Input with KVM, Industrial PC with Dual USB-C, Gaming Console Dual-C Port, USB-C Power Bank with Source/Sink.
Dual-Port USB-C Docking Station
The TPS65988DDK is a natural fit for dual-port USB-C docking stations that must negotiate 20 V/5 A upstream while simultaneously exposing a downstream port to a connected peripheral. Its integrated 25 mOhm bidirectional switches handle the upstream VBUS power path without external load switches, saving roughly 4-6 discretes per port. With USB-IF TID# 1099 certification, designers can avoid lab re-certification when porting PD 3.0 to docks. The I2C/SPI host interface allows the dock MCU to policy-engineer power role swaps and DisplayPort stream assignment in real time.
おすすめ
Thunderbolt 4 / USB4 Host Implementation
Host systems implementing Thunderbolt 4 or USB4 tunneling rely on the TPS65988DDK to manage dual Type-C ports at PD 3.0 with fast role swap and USB4 alternate-mode readiness. The integrated mux control signals steer the high-speed data lanes to the host CPU's retimer, while the integrated power switches carry 100 W per port to peripherals. The 56-VQFN 7x7 mm footprint suits compact mobile workstation layouts, and I2C host control enables platform firmware (BIOS/EC) to remap roles between USB4 and legacy modes.
おすすめ
USB-C Monitor Input with KVM
USB-C monitors that accept 90-100 W input and provide downstream USB hub/KVM channels benefit from the TPS65988DDK's dual-port capability: upstream Type-C for power and video, downstream Type-C for peripherals. The 25 mOhm switches support 5 A continuous charging while DisplayPort alternate-mode muxing routes the video to the panel's scalar. Fast role swap ensures the monitor remains a sink even if the host releases source role, satisfying PD 3.0 continuity requirements.
おすすめ
Industrial PC with Dual USB-C
Industrial PCs and HMIs requiring two USB-C ports find the TPS65988DDK ideal: PD 3.0 (USB-IF TID# 1099), dual-port mux control, and wide -40C to +85C operating range cover factory-floor environments. The integrated protection (OVP/OCP/OTP/RCP) on each VBUS path simplifies safety documentation for IEC 61131-2 compliance. GPIO outputs can drive status LEDs and external DC/DC enables for downstream peripherals.
おすすめ
Gaming Console Dual-C Port
Modern gaming consoles offering dual USB-C for power delivery to controllers and VR headsets can leverage the TPS65988DDK as the controller hub. The dual-port protocol engine assigns source or sink roles on the fly, while the 25 mOhm switches handle VR-headset 60-90 W charging without a separate load switch. DisplayPort alt-mode passthrough supports VR video when wired to a compatible headset.
おすすめ
USB-C Power Bank with Source/Sink
Battery-equipped devices such as USB-C power banks and portable hubs use the TPS65988DDK for bidirectional PD operation, where one port can sink to charge the internal battery while another port sources to a laptop. Fast role swap lets the bank instantly invert source/sink roles when the upstream cable reverses direction, and the integrated switches reduce BOM cost on each port by $0.20-0.30 USD versus discrete load switches.

設計ノート
Route CC1/CC2 lines to the Type-C connector with 0.5 mm differential-style traces and a 5.1 kOhm pull-down (sink) or pull-up (source) at the CC pins - this sets the default USB-C role advertised during connect, and the TPS65988DDK overrides the default only after PD negotiation completes. Always keep CC traces short (<10 mm) and away from high-speed DP/USB4 lanes to avoid CC crosstalk.
At 20 V/5 A continuous the integrated power switches dissipate up to 1.25 W per port (I^2 * R = 25 * 0.025). Estimated: with the VQFN 56-pin thermal pad on a 2 oz 1 oz copper pour of roughly 1 cm^2 total, theta_JA is in the 25-30 C/W range, yielding a 30-40 C rise. For >85 C ambient operation or sustained 5 A loads, expand copper to a 4 cm^2 pour or add thermal vias to the bottom layer.
Do not omit the external EEPROM - the TPS65988DDK requires a configuration image for port roles, GPIO behavior, and policy engine rules. Default boot mode fails without a valid image. Also: keep VBUS bulk capacitance below 100 uF per port to satisfy USB PD inrush current limits; exceeding this triggers SourceCap negotiation errors. Use TI's TPS65988 configuration tool to generate the EEPROM HEX before layout finalization.
Place the external 5 V LDO and input bulk caps near pin 53 (VDD). Keep the I2C pull-ups on the host interface (pins 9-10) at 4.7 kOhm when the host runs at 400 kHz Fast Mode. DisplayPort aux lines (pins 20-23) must be length-matched to within 50 mil and routed on the same layer to maintain AUX timing during alt-mode entry.
