3 Description

The TPS1641x is an integrated eFuse with accurate

power limit or current limit. The device provides robust

protection with integrated overcurrent protection,

overvoltage protection, IN to OUT short detection and

overtemperature protection.

TPS16410, TPS16411 devices provide ±5 power

limiting at 15 W for loads and it also provides

configurable blanking time for transient overload or

overcurrent events. TPS16410 and TPS16411 can be

used for low power circuits (LPCs) for 15-W power

limiting as per IEC60335 and UL60730 standards.

TPS1641x devices provide protection from adjacent

pin short and pin short to GND faults.

Applications such as backplane power protection in

PLC and DCS modules configure the current limit

with resistor on the ILIM pin. TPS16412, TPS16413

devices provide ±5 current limiting at 1.8 A for

loads and these devices also provide output slew rate

control with dVdT pin to charge large capacitive loads

at power up.

TPS1641x features IN to OUT short detection. The

device indicates IN to OUT short on the FLT pin. The

FLT pin can be either provided to MCU as Digital

Input or it can be used to drive an external PFET.

The devices are characterized for operation over a

junction temperature range of –40°C to +125°C.
