Description
The TPS2394EVM-652 is a -10-V to -80-V module using the TPS2394 hot-swap controller with external
MOSFET. At power on, the output is a current ramp to control inrush current. On an over-current
condition, the controller interrupts power to the load at high speed and signals load status. Operating
current, fault current and fault timer settings are hardware programmable.
