TI drives isolation technology forward with new solid-state relays that provide industry-leading reliability

New portfolio can aid make EVs safer while reducing resolution dimension up to 90% and cost by as substantially as 50%

DALLAS, May perhaps 10, 2022 /PRNewswire/ — Creating on much more than two decades of knowledge creating new isolation manufacturing systems and built-in circuits (ICs) for substantial-voltage systems, Texas Instruments (TI) (Nasdaq: TXN) these days launched a new portfolio of good-condition relays, which includes automotive-skilled isolated motorists and switches, that provide business-primary trustworthiness to help make electric automobiles (EVs) safer. The new isolated solid-state relays also give the smallest remedy dimensions when decreasing the bill-of-components (BOM) cost of powertrain and 800-V battery-management systems.

TI drives isolation technology forward with new solid-state relays that provide industry-leading reliability

New portfolio can aid make EVs safer whilst cutting down option sizing up to 90% and expense by as much as 50%

The TPSI3050-Q1 isolated swap driver with an built-in 10-V gate provide and the TPSI2140-Q1 1,400-V, 50-mA isolated switch both of those combine ability and sign isolation throughout a single barrier making use of a exclusive strategy that enhances dependability, while substantially decreasing remedy size and value compared to current electromechanical relays and good-state photorelays. The equipment are the initially in a new solid-state relays portfolio that will also contain ICs created for superior-voltage industrial purposes. To master much more about the gains of stable-condition relays, read through the technical article, “How to Attain Increased-Trustworthiness Isolation and a Lesser Alternative Sizing with Solid-Point out Relays.”

“Higher-voltage devices are turning out to be much more prevalent, especially with the greater adoption of EVs. At TI, we are strongly concentrated on acquiring new means for system designers to solve complex isolation challenges, this kind of as making certain reputable and risk-free car procedure as the field transitions to 800-V batteries, while also lessening option sizing and price tag,” mentioned Troy Coleman, vice president and standard supervisor of Power Switches, Interface and Lighting at Texas Devices. “By integrating additional functionality within our isolation engineering, our new reliable-state relays empower engineers to lower the dimension, charge and complexity of high-voltage electricity provides while sustaining the protection of up coming-era automotive and industrial systems.”

Obtain greater procedure reliability with built-in isolation technological innovation

The new reliable-condition relays can disconnect and link hundreds through a solitary isolation barrier in microseconds – when compared to milliseconds for electromechanical relays – to allow safer procedure of high-voltage automotive units. The TPSI3050-Q1, which provides bolstered isolation up to 5 kVRMS, also provides an functioning lifetime that’s 10 moments larger than electromechanical relays, which can degrade more than time. On top of that, the TPSI2140-Q1 presents simple isolation up to 3.75 kVRMS, enabling it to achieve additional than four periods bigger time-dependent dielectric breakdown dependability than reliable-point out photorelays.

Lower program dimensions and cost with built-in electricity and sign isolation

The strong-state relays integrate energy and signal transfer in a single chip although also removing at minimum 3 parts from their styles, significantly cutting down resolution dimensions whilst slicing BOM expenditures by as a lot as 50%. The TPSI3050-Q1 lessens solution sizing up to 90% as opposed to mechanical relay methods by integrating the functions of an isolated electricity offer, digital isolator and gate driver. The TPSI2140-Q1 minimizes answer measurement by as considerably as 50% compared to standard reliable-point out photorelay alternatives by integrating a signal area-result transistor and resistors, and getting rid of the require for a reed relay.

Boost safety of 800-V EV battery-management programs

Made for large-voltage measurements and insulation monitoring, the TPSI2140-Q1 is effective with a battery-pack check this kind of as the BQ79631-Q1 to detect insulation faults in 800-V battery-management devices quicker and with larger accuracy than stable-point out photorelays. The TPSI2140-Q1 enables the use of <1-MΩ resistors and withstands over 300% more avalanche current than traditional photorelays to help enable safer human-system interaction.

Package, availability and pricing

The TPSI3050-Q1 and TPSI2140-Q1 are available in pre-production, 1,000-unit quantities only on TI.com at US$1.99 and US$2.75, respectively. Engineers can evaluate these products with the TPSI3050Q1EVM and TPSI2140Q1EVM evaluation modules, available on TI.com for US$49 each.

Isolation products that are different by design

The solid-state relays are the latest addition to TI’s growing portfolio of products for isolating signals, power or both. Other new products include the UCC14240-Q1 isolated DC/DC bias-supply module, which leverages TI’s proprietary, integrated transformer technology to enable high power density, low electromagnetic interference and high reliability to improve EV driving ranges, and the AMC23C12, the industry’s first reinforced isolated comparator. The AMC23C12 combines the functions of standard comparators with a galvanic isolation barrier while reducing solution size by 50% and providing ultra-fast isolated bidirectional overcurrent and overvoltage detection in less than 400 ns.
