3 Description

The TPS1641x family are integrated eFuse devices

with accurate power limit or current limit. The device

family provides robust protection with integrated

overcurrent protection, overvoltage protection, IN to

OUT short detection, and overtemperature protection.

TPS16410 TPS16411, TPS16414, and TPS16415

devices provide ±5 power limiting at 15 W for loads

and it also provide configurable blanking time for

transient overload or overcurrent events. TPS16410,

TPS16411, TPS16414, and TPS16415 can be used

in 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

a resistor on the ILIM pin. TPS16412, TPS16413,

TPS16416, and TPS16417 devices provide ±6

current limiting at 1 A for loads and also provide

output slew rate control with dVdT pin to charge large

capacitive loads at power up.

TPS1641x features IN to OUT short detection and

indicate IN to OUT short on the FLT pin. The FLT pin

either provides to MCU as digital input or to drive an

external PFET.

The devices are characterized for operation over a

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