The TPS2662x family are compact, feature rich high voltage eFuses with a full suite ofprotection features. The wide supply input range of 4.5 V to 60 V allows control of many popular DCbus voltages. The device can withstand and protect the loads from positive and negative supplyvoltages up to ±60 V. The TPS26624 and TPS26625 devices support both input as well as outputreverse polarity protection feature. Integrated back to back FETs provide reverse current blockingfeature making the device suitable for systems with output voltage holdup requirements during powerfail and brownout conditions. Load, source and device protection are provided with many adjustablefeatures including overcurrent, output slew rate and overvoltage, undervoltage thresholds. Theinternal robust protection control blocks along with the high voltage rating of the TPS2662x familyhelps to simplify the system designs for Surge protection.
The TPS26620, TPS26622 and TPS26624 feature Latch off and TPS26621, TPS26623 and TPS26625feature 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.
