DESCRIPTION
Each TPS2343 contains main supply power
control, auxiliary supply power control, power
FETs for 12-V, 12-V and auxiliary 3.3-V supplies,
VIO control, and digital control for two slots.
The main power control circuits start with all
supplies off and all outputs are held off until
PGOOD is asserted, indicating that system
supplies are valid. Then, when power enable is
asserted, the control circuit applies constant
current to the gates of the power FETs, allowing
each FET to ramp load voltage linearly. Each
supply can be programmed for a desired ramp
rate by selecting the appropriate gate capacitor.
The TPS2343 monitors load current and regulates
peak current to prevent disturbances to the
system power rails. If load current remains
regulated for longer than 5 ms, that slot is latched
off.
Logic inputs to the TPS2343 access all functions
of the TPS2343. All status information from the
TPS2343 is available on logic outputs.
