3 Description

The TPS1663x is an easy to use, positive 60 V, 6-A

eFuse with a 31-mΩ integrated FET. Protection for

the load, source and eFuse itself are provided along

with adjustable features such as accurate overcurrent

protection, fast short circuit protection, output slew

rate control, overvoltage protection and undervoltage

lockout. The TPS16332 device integrates adjustable

output

power

limiting

(PLIM)

functionality

that

simplifies and enables compliance to standards such

as

IEC61010-1

and

UL1310.

The

device

also

includes adjustable overcurrent functionality. PGOOD

can be used for enable and disable control of the

downstream DC-DC converters.

A shutdown pin provides external control for enabling

and disabling the internal FET as well as placing the

device in a low current shutdown mode. For system

status monitoring and downstream load control, the

device provides fault and a precise current monitor

output. The MODE pin allows flexibility to configure

the device between the two current-limiting fault

responses (latch off and auto-retry).

The devices are available in a 4-mm × 4-mm 24-pin

VQFN package and are specified over a –40°C to

+125°C temperature range.
