The TPS1641x is an integrated eFuse with accurate power limit or current limit. The device integrates an NFET with R_ON of 152 mΩ. TPS16410, TPS16411, TPS16414 and TPS16415 provide power limiting whereas the TPS16412, TPS16413, TPS16416 and TPS16417 provide current limiting. The TPS16410, TPS16411, TPS16414 and TPS16415 can provide 15-W accurate power limiting for low power circuit (LPCs) as per IEC60335 and UL60730 standards. TPS16410, TPS16411, TPS16412 and TPS16413 also provide IN to OUT short detection and its indication on FLT output. IN to OUT short detection eliminates the need of additional eFuse or power limiting circuit in case of IN to OUT short test for IEC60335, UL60730, and similar standards. FLT can be used as input for MCU or it can be used to drive an external PFET. TPS1641x devices also provide protection from adjacent pin short and pin short to GND faults.

The TPS1641x device also provide configurable blanking time (IDLY or PDLY) and overcurrent protection (IOCP) for transient loads. Load such as motors need higher current for start-up. Blanking time is useful for providing higher current for start-up of loads such as motors.

TPS1641x devices have overvoltage protection (OVP), overtemperature protection, and adjustable output slew rate control (dvdt). Vcc and FLT are rated up to 60 V and can provide protection up to 60 V with an external PFET.
