5 TPS650861 Programming Information

The user-programmable TPS650861 has two banks of one-time programmable (OTP) memory that allow you to fully customize the output voltages, sequencing, GPIO control, and more to best meet your system needs. The entire programming process is outlined in the TPS65086100 Non-Volatile Memory Programming Guide. Other resources to support the TPS650861 programming process include:

• The TPS65086100 OTP Generator takes in your specific requirements and then automatically generates the I²C commands needed to program the TPS650861.
• The BOOSTXL-TPS650861 BoosterPack™, which enables custom programming of the OTP memory of the TPS650861 for rapid prototyping and quicker time to market.
• The BOOSTXL-TPS650861 EVM User’s Guide, which provides a guideline to program the OTP memory of the TPS650861 using BOOSTXL-TPS650861 BoosterPack™, an MSP430F5529 LaunchPad™ development kit, and IPG-UI EVM GUI software.
• Training videos on TI.com that provide an overview and step through the DIY PMIC programming process.

When generating a custom OTP file for programming, TI recommends starting with one of the template OTP files from the TPS650864x pre-programmed variants if only modifying a few rails. These pre-programmed OTP Generator files are available on the TPS650861 product folder, under the Design and development section.
