3 Description

The TPS2663x devices are easy to use, positive

60 V and 6-A eFuse with a 31-mΩ integrated

FET. It features a B-FET driver to control an

external N-channel FET in the system designs

that require protection from input reverse polarity

faults and reverse current blocking. The device

incorporates robust protection features that simplify

system designs requiring protection during system

tests like IEC61000-4-5 industrial surge tests. The

device features an adjustable output power limiting

(PLIM) functionality that simplifies the system design

requiring compliance in accordance to the standards

like IEC61010-1 and UL1310. Additional protection

features include adjustable overcurrent protection,

fast short circuit protection, output slew rate control,

overvoltage protection and undervoltage lockout.

For system status monitoring and downstream load

control, the device provides fault and a precise

current monitor output. PGOOD can be used for

enable and disable control of the downstream DCDC

converters. The MODE pin allows flexibility to

configure the device between the two current-limiting

fault responses (latch off and auto-retry).
