Industrial eFuse with integrated reverse polarity protection

The Texas Instruments TPS2662x family are compact, feature-rich high-voltage eFuses with a full set of protection features. The wide supply input range of 4.5V to 57V enables control of many popular DC bus voltages. The device can endure and protect the loads from positive and negative supply voltages up to ±60V. The TPS26624 and TPS26625 devices support both inputs as well as an output reverse polarity protection feature. Combined back to back FETs offer a reverse current blocking feature making the device ideal for systems with output voltage holdup demands during power fail and brownout conditions. Load, source and device protection are given 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 family help 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 overcurrent fault events. The devices are offered in a 3mm x 3mm 10-pin SON package and are specified over a –40C to +125C temperature range.
