2.7-V to 40-V 152-mΩ 1.8-A eFuse with output power limiting

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 15W for loads and also provide

configurable blanking time for transient overload or overcurrent events. Use

TPS16410, TPS16411, TPS16414, and TPS16415 in low-power circuits (LPCs) for 15W

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 1A 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 from –40°C to +125°C.
