TPS65987DDHRSHR 概要
A USB Type-C PD controller is a specialized power management IC that manages power delivery and data communication over a USB Type-C connector. It handles cable detection, orientation, and power role negotiation (source, sink, or dual-role), enabling devices to negotiate voltage and current levels up to 100W. This controller sits between the USB connector and the system's power management unit, ensuring safe and efficient power transfer while supporting alternate modes like DisplayPort or Thunderbolt.
Key features include integrated power switches for both source and sink paths, support for Dual-Role Power (DRP), Sink, and Source roles, and alternate mode configuration. The TPS65987D communicates using the USB PD protocol and includes a host interface for configuration and status monitoring. The device is designed for high-speed USB applications, with support for USB 3.1 data rates and integrated power path management.
Technically, the TPS65987D integrates the CC logic, PD protocol engine, and power switches in a single package, reducing external component count and board space. It includes protection features such as overcurrent and overvoltage protection, and supports firmware updates via the host interface. The device is configurable through I2C or SPI, allowing flexible system integration.
Typical applications include laptops, docking stations, monitors, power adapters, and other USB Type-C enabled devices that require PD negotiation and power switching. The integrated power switches simplify the design and reduce BOM cost, making it ideal for space-constrained applications.
When designing with this device, ensure proper decoupling on the 3.3V supply and follow the recommended layout for the VQFN package to manage thermal performance. The device is currently in NRND (Not Recommended for New Designs) status, so consider the TPS65988 as a drop-in replacement for new designs.

設計ノート
Ensure proper decoupling on the 3.3V supply with 0.1uF and 10uF capacitors placed close to the VIN_3V3 pin. The TPS65987DDHRSHR requires a clean power supply for reliable PD negotiation. Refer to the datasheet's recommended layout for capacitor placement.
Follow the VQFN package layout guidelines, including thermal pad soldering and via placement for heat dissipation. The 7x7 mm package has an exposed pad that must be connected to ground for proper thermal performance. Use a 2x2 via array under the pad.
Since the TPS65987DDHRSHR is NRND, avoid using it in new designs. For new designs, use the TPS65988, which is pin-to-pin compatible. If you must use this part, ensure you have sufficient inventory for the product lifecycle.
