42-V, 2-A industrial eFuse with integrated reverse input polarity protection

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
