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.
