Frequently Asked Questions
What is the PTPS259621DDAR and what protection features does it offer?
The PTPS259621DDAR is a single-channel eFuse (electronic fuse) IC from Texas Instruments that provides adjustable overcurrent protection with a current range of 0.13A to 2A and fast overvoltage protection. With an 85 mΩ on-resistance and an accurate current monitor, it replaces traditional fuses in power path protection applications while enabling real-time current measurement.
What voltage and current range does the PTPS259621DDAR support?
The PTPS259621DDAR operates across an input voltage range of 2.7V to 19V and supports an adjustable current threshold between 0.13A and 2A. The adjustable threshold allows engineers to tailor the overcurrent trip point for specific load requirements, making it suitable for a wide variety of power rail protection scenarios from low-power sensors to high-current industrial loads.
What package does the PTPS259621DDAR use and what are its thermal characteristics?
The PTPS259621DDAR is packaged in an 8-pin SOIC (Small Outline IC) with a heat sink slug (JESD-30 code R-PDSO-G8, package style: SMALL OUTLINE, HEAT SINK/SLUG). The integrated thermal slug improves heat dissipation, which is important for the 85 mΩ on-resistance path when conducting up to 2A continuously, helping maintain junction temperature within safe limits.
What are the typical applications for the PTPS259621DDAR?
The PTPS259621DDAR is commonly used in server blade hot-swap circuits, PCIe add-in card power protection, telecom line cards, and industrial automation power distribution. Its accurate current monitor output is valuable in battery management systems and power budgeting applications where load current must be measured and reported to a host microcontroller or power management IC.
When was the PTPS259621DDAR introduced and is it suitable for new designs?
The PTPS259621DDAR was introduced on May 11, 2019, and represents a relatively recent eFuse design from Texas Instruments. While its YTEOL value is listed as 0, designers should check TI's current lifecycle status before committing to new designs, and may consider contacting TI or authorized distributors to confirm availability and recommended alternatives if needed.
