3 Description

The TPS2662x family are compact, feature rich high

voltage eFuses with a full suite of protection features.

The wide supply input range of 4.5 V to 60 V

allows control of many popular DC bus voltages.

The device can withstand and protect the loads from

positive and negative supply voltages up to ±60 V.

The TPS26624 and TPS26625 devices support both

input as well as output reverse polarity protection

feature. Integrated back to back FETs provide reverse

current blocking feature making the device suitable

for systems with output voltage holdup requirements

during power fail and brownout conditions. Load,

source and device protection are provided with many

adjustable features including overcurrent, output slew

rate and overvoltage, undervoltage thresholds. The

internal robust protection control blocks along with the

high voltage rating of the TPS2662x family helps to

simplify the system designs for Surge protection.

The TPS26620, TPS26622 and TPS26624 feature

latch-off and TPS26621, TPS26623 and TPS26625

feature auto-retry functionality, which are the

overtemperature and overcurrent fault events.

The devices are available in a 3 mm × 3 mm 10-pin

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

+125°C temperature range.
