STMicroelectronics 1 Voltage Supervisor Electronic Fuse, 14-Pin HTSSOP Package, 16 V Reset Threshold, Operating STEF01FTR

STMicroelectronics STEF01FTR is a highly reliable 1 voltage supervisor electronic fuse integrated circuit packaged in a 14-pin HTSSOP surface mount form factor. It has a reset threshold voltage of 16 V and operates within a voltage supply range of 4 V minimum up to 48 V maximum with an absolute maximum input voltage rating of 55 V.

Engineered for robust performance across temperature extremes from -40°C to 125°C, this device integrates an open collector/open drain output driver for flexible control and monitoring in electronic circuits.

The supervisor includes advanced power management features such as programmable undervoltage lockout, an adjustable output clamp voltage that can be set between 10 and 52 volts, and a soft-start time that can be tuned to optimize device startup behavior.

Protection capabilities include short-circuit current limiting, programmable overload current limit, and thermal protection that can either latch or auto-retry, safeguarding the power system and downstream circuitry from damage.

The typical continuous current is 4 amperes with a low N-channel on-resistance of approximately 30 milliohms, ensuring efficient conduction and minimal power loss. Its compact HTSSOP package dimensions (5.1 mm length × 4.5 mm width × 1.2 mm height) allow easy mounting on compact PCBs.

This product is primarily used in power management IC applications for industrial machines, embedded electronics, automotive electronics, and other demanding fields requiring stable voltage supervision and fault protection.
