The device operates with an input voltage range of 0.8V to 5.5V and a separate bias supply of 2.5V to 5.5V, which ensures low on-resistance across the entire input voltage range. The controlled slew rate limits inrush current during turn-on, protecting downstream components. When the switch is disabled, the QOD feature rapidly discharges the output capacitance through an internal resistor, ensuring a clean power-down. The device consumes only 20 uA quiescent current and 1 uA shutdown current at VBIAS=5V.","working_principle":"The TPS22959DNYT integrates a low-resistance N-channel MOSFET with control logic and protection circuits. (1) Main Switch: An N-channel power MOSFET with 4.4 mOhm on-resistance connects VIN to VOUT when enabled. A charge pump generates the gate drive voltage from the VBIAS supply to fully enhance the MOSFET even when VIN is as low as 0.8V. (2) Controlled Turn-On: The slew rate control circuit gradually increases the gate voltage, resulting in a controlled rise time of 2663 us at VIN=5V. This limits the inrush current into downstream capacitors, preventing voltage droop on the input rail. (3) Quick Output Discharge: When the switch is disabled, an internal discharge resistor (QOD) connects from VOUT to GND, rapidly discharging the output capacitance to ensure a clean power-down sequence. (4) Bias Supply: The separate VBIAS pin powers the internal control circuitry and charge pump. This allows the switch to maintain low RDS(on) even with very low VIN voltages.","pin_description":"<table><tr><th>Pin<\/th><th>Name<\/th><th>Type<\/th><th>Function<\/th><\/tr><tr><td>1<\/td><td>VIN<\/td><td>Power<\/td><td>Input voltage (0.8-5.5V)<\/td><\/tr><tr><td>2<\/td><td>VIN<\/td><td>Power<\/td><td>Input voltage (0.8-5.5V)<\/td><\/tr><tr><td>3<\/td><td>ON<\/td><td>Input<\/td><td>Switch enable (active high)<\/td><\/tr><tr><td>4<\/td><td>VBIAS<\/td><td>Power<\/td><td>Bias supply for charge pump (2.5-5.5V)<\/td><\/tr><tr><td>5<\/td><td>GND<\/td><td>Ground<\/td><td>Ground reference<\/td><\/tr><tr><td>6<\/td><td>QOD<\/td><td>I\/O<\/td><td>Quick output discharge pin<\/td><\/tr><tr><td>7<\/td><td>VOUT<\/td><td>Output<\/td><td>Switch output<\/td><\/tr><tr><td>8<\/td><td>VOUT<\/td><td>Output<\/td><td>Switch output<\/td><\/tr><\/table>","application_scenarios":"<ul><li>Server and networking equipment power sequencing with 15A current handling<\/li><li>SSD and storage device power switching with inrush current limiting<\/li><li>Portable electronics power rail management with ultra-low 4.4 mOhm RDS(on)<\/li><li>Hot-plug and hot-swap power control with QOD for clean power-down<\/li><\/ul>","alternative_models":"<table><tr><th>Manufacturer<\/th><th>Part Number<\/th><th>Package<\/th><th>Notes<\/th><\/tr><tr><td>TI<\/td><td>TPS22966DNYT<\/td><td>WSON-8<\/td><td>6A, dual channel<\/td><\/tr><tr><td>TI<\/td><td>TPS22975DNYT<\/td><td>WSON-8<\/td><td>8A, adjustable rise time<\/td><\/tr><tr><td>onsemi<\/td><td>NCP45561IMNTWG<\/td><td>DFN-8<\/td><td>5.5V, 12A load switch<\/td><\/tr><tr><td>Microchip<\/td><td>MIC94070YC6<\/td><td>SC-70-6<\/td><td>2A, smaller package<\/td><\/tr><\/table>"},"_links":{"self":[{"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/posts\/7077","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/comments?post=7077"}],"version-history":[{"count":0,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/posts\/7077\/revisions"}],"wp:attachment":[{"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/media?parent=7077"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/categories?post=7077"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/tags?post=7077"},{"taxonomy":"chip_brand","embeddable":true,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/chip_brand?post=7077"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
