Abstract
A programmable power distributing sequencer including a plurality of internal regulators, an internal memory adapted to store a user programmable script including instructions for sequentially enabling and disabling the regulators, and a controller adapted to enable and disable the regulators based on the script. The controller may receive the user programmable script from a programming source, such as an applications processor, an external memory, or external programming device. Before using the user programmable script, the controller may execute a default script stored in the internal memory to initially power up the programming source. The sequencer may further include an external port for similarly controlling one or more external regulators. The port may also be used to connect multiple sequencers together, such as in a cascaded, hierarchical, and/or redundant manner. Additionally, the sequencer may include a fault detection module for detecting faulty operating regulators.
