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 are the over
temperature and over current 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.
