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).
