Other Parts Discussed in Thread: TPS25750, BQ25756, BQ25713, BQ25731
What is the TPS25751?
- The TPS25751 is a USB Type-C® and USB PD Controller with Integrated Power Switches Optimized for Power Applications. The TPS25751 is the direct follow on to the TPS25750, and implements the same functionality of the TPS25750 while adding new features and improving functionality.
Why migrate to the TPS25751?
-
The TPS25751 improves the I2C functionality for the supported battery chargers. There are a couple of know issues found in the TPS25750 that are addressed in the TPS25751 specifically with the PD + battery charger pairing.
- The TPS25751 implements new features like liquid detection and programmable power supply (PPS)
- Adds support for new TI battery chargers such as the BQ25756
Is it difficult to migrate to the TPS25751?
-
No, the TPS25750 and TPS25751 are pin to pin compatible with one another. If you have a design that is utilizing the TPS25750 and wish to migrate to the TPS25751, you can remove the TPS25750 and populate the TPS25751 instead.
- The TPS25751 integrates the same functionality as the TPS25750,so any features supported on the TPS25750 will also be supported in the TPS25751.
Is there a scenario where I should use the TPS25750 instead of the TPS25751?
- No, since the TPS25751 incorporates the same features while improving functionality so all new designs should use the TPS25751 instead of the TPS25750.
