Sequencers 101

TI has a variety of both analog and digital sequencers and system health monitors used in a wide variety of applications. Our analog LM388X sequencers are simple to use and easy to design with, to ensure systems consisting of 3 to 9 rails are powered up and powered down in the proper order. The UCD90XXX family of PMBus / I2C addressable digital power supply sequencers are for more complex systems, and enable sequencing up to 32 rails (or more when devices are cascaded). These devices allow designers to monitor various system rails, adjust timing delays during system turn on and turn off, improve system reliability, and assist in system debugging in the event of an error.

1. Working with TI Sequencers

Here, you will find a series of design and application notes, blogs, and videos that showcase how the sequencers can be used in a number of applications, and hopefully address some issues you might encounter when using this family of devices.

3. Software Support

The UCD90XXX sequencer family can be programmed and configured in PMBus and I2C, but TI’s easy to use Fusion Digital Power™ GUI enables the designer to do as much without ever writing a single line of code. Below you will find some training videos for using this GUI as well as some other application notes to support programming in PMBus.
