The device integrates a 88m\u03a9 N-channel MOSFET with slew-rate controlled turn-on, preventing power bus disturbances during hot-swap events. Current limit is programmed via an external resistor on the ISET pin, adjustable from 0.4A to 2A minimum. The FPF2700 variant responds to overloads exceeding the blanking time by disconnecting the load and automatically retrying after a restart timer. Additional features include active-LOW ON control, undervoltage lockout, power-good output, and fault flag output for monitoring. The SOIC-8 package is suitable for space-constrained applications.","working_principle":"The FPF2700MX operates as a high-side N-channel MOSFET switch controlled by an internal charge pump that generates the gate drive voltage above the input supply. The ON pin (active LOW) enables the switch; when asserted, the charge pump drives the MOSFET gate with a controlled slew rate, limiting inrush current during hot-plug events. The ISET pin sets the current limit threshold through an external resistor to ground. When load current exceeds the programmed limit for a fixed blanking time, the FPF2700 disconnects the load and initiates an auto-restart sequence after a cool-down period. The Power Good (PGOOD) pin is an open-drain output that asserts when VOUT reaches 90% of VIN. The FLAGB pin indicates fault conditions (overcurrent, UVLO, or overtemperature) as an active-low open-drain signal. Overtemperature shutdown protects the device during sustained overload conditions.","pin_description":"<table border='1'><tr><th>Pin<\/th><th>Name<\/th><th>Type<\/th><th>Description<\/th><\/tr><tr><td>1<\/td><td>VIN<\/td><td>Power<\/td><td>Input supply voltage (2.8V to 36V); powers switch and internal circuitry<\/td><\/tr><tr><td>2<\/td><td>PGOOD<\/td><td>Output<\/td><td>Power Good open-drain output; asserts when VOUT reaches 90% of VIN<\/td><\/tr><tr><td>3<\/td><td>ISET<\/td><td>Input<\/td><td>Current limit set; resistor to GND programs 0.4A-2A current limit<\/td><\/tr><tr><td>4<\/td><td>ON<\/td><td>Input<\/td><td>On control; active LOW enables the switch<\/td><\/tr><tr><td>5<\/td><td>GND<\/td><td>Ground<\/td><td>Device ground<\/td><\/tr><tr><td>6<\/td><td>NC<\/td><td>-<\/td><td>No connect; leave open or connect to GND<\/td><\/tr><tr><td>7<\/td><td>FLAGB<\/td><td>Output<\/td><td>Fault flag; active-low open-drain indicates current limit, UVLO, or thermal shutdown<\/td><\/tr><tr><td>8<\/td><td>VOUT<\/td><td>Power<\/td><td>Switch output to load<\/td><\/tr><\/table>","application_scenarios":"<ul><li><b>Hot-Swap Power Insertion:<\/b> Controls inrush current when plugging in PCB modules or drives, with slew-rate limiting preventing bus voltage droop on live backplanes<\/li><li><b>Hard Disk Drive Power:<\/b> Switches and protects HDD power rails with adjustable current limiting matching drive startup surge profiles<\/li><li><b>Motor Drive Protection:<\/b> Limits motor stall current and provides auto-restart after fault clearing in brushed DC motor applications<\/li><li><b>Telecom Power Distribution:<\/b> Distributes 12V\/24V\/36V power rails to line cards with fault isolation and status monitoring via PGOOD and FLAGB<\/li><li><b>Digital Camera Power Control:<\/b> Sequences power to imaging modules and flash units with controlled turn-on and overcurrent protection<\/li><\/ul>","alternative_models":"<table border='1'><tr><th>Model<\/th><th>Manufacturer<\/th><th>Ilimit<\/th><th>Vin<\/th><th>Key Difference<\/th><\/tr><tr><td>FPF2701MX<\/td><td>onsemi<\/td><td>0.4-2A<\/td><td>2.8-36V<\/td><td>Latching fault response (no auto-restart)<\/td><\/tr><tr><td>FPF2702MX<\/td><td>onsemi<\/td><td>0.4-2A<\/td><td>2.8-36V<\/td><td>External fault management mode<\/td><\/tr><tr><td>FPF2700MPX<\/td><td>onsemi<\/td><td>0.4-2A<\/td><td>2.8-36V<\/td><td>Same function in MLP 3x3mm package<\/td><\/tr><tr><td>TPS259521LWR<\/td><td>TI<\/td><td>0.1-2A<\/td><td>4.5-60V<\/td><td>Higher voltage, wider current range<\/td><\/tr><tr><td>LTC4365CTS8<\/td><td>ADI<\/td><td>-<\/td><td>2.5-36V<\/td><td>Overvoltage\/UV lockout protector (not a switch)<\/td><\/tr><\/table>"},"_links":{"self":[{"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/posts\/6394","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/comments?post=6394"}],"version-history":[{"count":0,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/posts\/6394\/revisions"}],"wp:attachment":[{"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/media?parent=6394"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/categories?post=6394"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/tags?post=6394"},{"taxonomy":"chip_brand","embeddable":true,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/chip_brand?post=6394"}],"curies":[{"name":"\u062f\u0628\u0644\u064a\u0648 \u0628\u064a","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
