SLVSFQ6 – NOVEMBER 2020  
TPS26400 42-V, 2-A eFuse With Integrated Reverse Input Polarity Protection  
1 Features  
3 Description  
4.2-V to 42-V operating voltage, 45-V absolute  
maximum  
Integrated reverse input polarity protection down to  
–42 V  
– Zero additional components required  
Integrated back to back MOSFETs with 150-mΩ  
total RON  
0.1-A to 2.23-A adjustable current limit (±5%  
accuracy at 1 A)  
Load protection during Surge (IEC 61000-4-5) with  
suitable TVS  
IMON current indicator output (±8.5% accuracy)  
Low quiescent current, 300-μA in operating, 20-μA  
in shutdown  
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.  
Adjustable UVLO, OVP cut off, output slew rate  
control  
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).  
Reverse current blocking  
Available in easy-to-use 16-pin HTSSOP and 24-  
pin VQFN packages  
Selectable current-limiting fault response options  
(auto-retry, latch Off, circuit breaker modes)  
2 Applications  
HMI Power protection in Factory Automation  
Fire Safety Systems  
Electronic Thermostats and Video Doorbells  
Industrial PCs  
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
