Description

The TPS2340A contains main supply power control, auxiliary supply power control, power FETs for 12 V, 12 V and auxiliary 3.3 V supplies,and a serial interface for communications with and control of slots. Each TPS2340A contains supply control and switching for two slots.

The main power control circuits start with all supplies off and hold all supplies off until power to the TPS2340A is valid on all positive supplies.When power is requested via the serial interface,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 a gate capacitor for the power FET for that supply.The power control circuits also monitor load current and latch off that slot if the load current exceeds a programmed maximum value. In addition, once the 12-V, the 5-V, and the 3.3-V FETs are fully enhanced, the load voltage is monitored. If load voltage drops out of specification after these FETs are fully enhanced,the slot latches off. This provides another level of protection from load fault.
