The TPS26400 devices are compact, feature rich high voltage eFuses with a full suite of protection features. The wide supply input range of 4.2 to 42 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 ±42 V. 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 TPS26400 helps to simplify the system designs for Surge protection.

A shutdown pin provides external control for enabling and disabling the internal FETs as well as placing the device in a low current shutdown mode. For system status monitoring and downstream load control, the device provides fault and precise current monitor output. The MODE pin allows flexibility to configure the device between the three current-limiting fault responses (circuit breaker, latch off, and Auto-retry modes).

The device is available in a 5-mm × 4.4-mm 16-pin HTSSOP as well as 5-mm x 4-mm 24-pin VQFN package and are specified over a –40°C to +125°C temperature range
