DESCRIPTION  
FAULT  
The TPS2300 and TPS2301 are dual-channel hot-  
swap controllers that use external N-channel  
MOSFETs as high-side switches in power  
applications. Features of these devices, such as  
overcurrent protection (OCP), inrush current control,  
output-power status reporting, and the ability to  
discriminate between load transients and faults, are  
critical requirements for hot-swap applications.

The TPS2300/01 devices incorporate undervoltage lockout (UVLO) and power-good (PG) reporting to ensure the  
device is off at start-up and confirm the status of the output voltage rails during operation. Each internal charge  
pump, capable of driving multiple MOSFETs, provides enough gate-drive voltage to fully enhance the N-channel  
MOSFETs. The charge pumps control both the rise times and fall times (dv/dt) of the MOSFETs, reducing power  
transients during power up/down. The circuit-breaker functionality combines the ability to sense overcurrent  
conditions with a timer function; this allows designs such as DSPs, that may have high peak currents during  
power-state transitions, to disregard transients for a programmable period.
