TPS2383B
SLUS565G – JULY 2003 – REVISED AUGUST 2005
APPLICATION INFORMATION (continued)
The TPS2383B has circuit resources that are common to each port and circuit resources that are shared by all
ports. Five independent state machines are used to control the common and shared PSEPM resources. Port
control, UV/OV/OC and overload protection are all features that are common to each port. Data acquisition and
power ramping are shared functions for all the ports.
The master sequencer state machine is used to index the port presently being serviced and to distribute the
shared resources to the currently selected port. The single master sequencer is responsible for incrementally
accessing ports 1 through 8 and allowing those ports to process register data when they are accessed. Ports 1
through 8 each have a port sequencer, which controls all the power enabling and fault protection functions of the
port per the register commands. The A/D has an A/D Sequencer that triggers, cycles and signals the port and
master sequencer upon completion. The ramp sequencer controls the power ramping resource and is triggered
by the port and master sequencer and provides a completion signal when power ramping is over.
