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
