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. ## Active production — no LTB clock ticking The TPS2350PW carries an active lifecycle status from Texas Instruments. The ROHS3 compliance is current, so it passes European and California regulatory requirements as-is. For a BOM line that needs a -48V hot swap controller with multi-channel capability, this part has no supply-risk clock running against it. ## Industrial temperature range — telecom cabinet reality Rated for -40°C to 85°C operating temperature, the TPS2350PW covers the thermal envelope of outdoor telecom cabinets, central office environments, and unventilated equipment bays. 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","stockQuantity":0,"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},"ai":{"faq":[{"question":"Does TPS2350PW work for -48V systems?","answer":"Yes, it is specifically designed for -48V applications.
