New portfolio can aid make EVs safer while decreasing remedy size up to 90% and charge by as a lot as 50%
DALLAS, May well 10, 2022 /PRNewswire/ — Constructing on extra than two decades of knowledge creating new isolation producing systems and integrated circuits (ICs) for substantial-voltage methods, Texas Devices (TI) (Nasdaq: TXN) these days launched a new portfolio of solid-condition relays, together with automotive-certified isolated motorists and switches, that produce field-main reliability to enable make electric motor vehicles (EVs) safer. The new isolated stable-condition relays also provide the smallest remedy dimensions when reducing the invoice-of-elements (BOM) expense of powertrain and 800-V battery-management devices. For a lot more data, see ti.com/ssr-pr.
The TPSI3050-Q1 isolated switch driver with an integrated 10-V gate supply and the TPSI2140-Q1 1,400-V, 50-mA isolated switch equally integrate electrical power and signal isolation across a single barrier using a exceptional strategy that improves reliability, whilst significantly lowering resolution measurement and value in comparison to present electromechanical relays and strong-condition photorelays. The gadgets are the initial in a new stable-condition relays portfolio that will also contain ICs intended for large-voltage industrial purposes. To master additional about the advantages of reliable-condition relays, read through the specialized report, “How to Realize Higher-Trustworthiness Isolation and a Lesser Remedy Measurement with Solid-Point out Relays.”
“Substantial-voltage methods are getting to be more prevalent, specifically with the increased adoption of EVs. At TI, we are strongly targeted on finding new methods for method designers to solve sophisticated isolation problems, this kind of as ensuring reliable and safe car or truck procedure as the market transitions to 800-V batteries, while also reducing option size and charge,” stated Troy Coleman, vice president and normal manager of Electric power Switches, Interface and Lighting at Texas Instruments. “By integrating more performance within just our isolation engineering, our new solid-condition relays help engineers to cut down the dimension, cost and complexity of large-voltage electric power supplies while maintaining the security of following-era automotive and industrial techniques.”
Attain higher system trustworthiness with built-in isolation technologies
The new reliable-point out relays can disconnect and hook up masses by way of a solitary isolation barrier in microseconds – in contrast to milliseconds for electromechanical relays – to allow safer operation of high-voltage automotive programs. The TPSI3050-Q1, which presents bolstered isolation up to 5 kVRMS, also delivers an operating life span that’s 10 instances bigger than electromechanical relays, which can degrade over time. On top of that, the TPSI2140-Q1 presents standard isolation up to 3.75 kVRMS, enabling it to reach much more than four periods higher time-dependent dielectric breakdown dependability than stable-point out photorelays.
Lower system size and cost with integrated electricity and sign isolation
The solid-condition relays integrate energy and sign transfer in a one chip when also eliminating at least a few parts from their models, drastically minimizing resolution size though cutting BOM fees by as considerably as 50%. The TPSI3050-Q1 decreases remedy size up to 90% when compared to mechanical relay options by integrating the features of an isolated power supply, digital isolator and gate driver. The TPSI2140-Q1 cuts down alternative measurement by as much as 50% when compared to common strong-condition photorelay answers by integrating a signal subject-influence transistor and resistors, and doing away with the need for a reed relay.
Increase protection of 800-V EV battery-management units
Designed for high-voltage measurements and insulation checking, the TPSI2140-Q1 functions with a battery-pack monitor this sort of as the BQ79631-Q1 to detect insulation faults in 800-V battery-administration programs more quickly and with bigger precision than good-condition photorelays. The TPSI2140-Q1 permits the use of <1-MO 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.
