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.
