It manages three independent channels, letting you sequence or protect multiple loads from a single controller. The supply range covers -80V to -12V, so it handles the full -48V telecom rail including transients and cold-crank dips. Programmable features — current limit, fault timeout, overvoltage protection (OVP), slew rate, and undervoltage lockout (UVLO) — are all set with external resistors and capacitors, no I2C or digital interface needed. ## Three channels — why that matters for a -48V board Three channels in a single 14-TSSOP package means one controller can gate three separate -48V feeds. Typical use: powering two line cards and a fan tray from the same backplane slot, or implementing OR-ing plus inrush limiting on redundant -48V feeds. Each channel has its own gate drive and fault reporting, so a short on one rail doesn't take down the others. The controller itself doesn't contain the pass FETs — you supply external N-channel MOSFETs sized for your load current, which keeps the power dissipation off the controller and lets you scale the current rating per channel. The ROHS3 compliance is current, so it passes European and California regulatory requirements as-is. ## Industrial temperature range — telecom cabinet reality The -40°C low end handles cold-start conditions in remote shelters; the 85°C top end covers the internal ambient near a -48V rectifier shelf or a densely populated line card. No need to derate or add a heater for typical telecom deployment.","metaTitle":"TI TPS2350PW Hot Swap Controller, -48V, 3-Ch, 14-TSSOP","metaDescription":"Texas Instruments TPS2350PW -48V hot swap controller, 3 channels, programmable UVLO/OVP/current limit, -40 to 85°C, active production.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Analog & Data Acquisition"],"specifications":{"Type":"Hot Swap Controller","Package":"Tube","Features":"Auto Retry","Applications":"-48V","Mounting Type":"Surface Mount","Package / Case":"14-TSSOP (0.173\\\", 4.40mm Width)","lifecycle_stage":"eol_hot","Voltage - Supply":"-80V ~ -12V","Internal Switch(s)":"No","Number of Channels":"3","Operating Temperature":"-40°C ~ 85°C","Programmable Features":"Current Limit, Fault Timeout, OVP, Slew Rate, UVLO","Supplier Device Package":"14-TSSOP"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$6.48","priceTiers":[{"qty":1,"price":"$6.48000","currency":"USD"},{"qty":10,"price":"$5.82300","currency":"USD"},{"qty":25,"price":"$5.50440","currency":"USD"},{"qty":100,"price":"$4.77060","currency":"USD"},{"qty":250,"price":"$4.52600","currency":"USD"},{"qty":500,"price":"$4.06116","currency":"USD"},{"qty":1000,"price":"$3.46200","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/40add3d27c925af6cd75530afa909087.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS2350PW/alternatives.json"},"ai":{"faq":[{"question":"Does TPS2350PW work for -48V systems?","answer":"Yes, it is specifically designed for -48V applications.
