24 PRODUCT UPDATE Issue 2 2024 Power Electronics Europe www.power-mag.com lighting; telecom SMPS; solar inverters; welding equipment; induction heating; motor drives; and battery chargers. Measuring 10.42 mm by 8 mm by 1.65 mm, the SiHR080N60E’s compact PowerPAK 8 x 8LR package features a 50.8 % smaller footprint than the D?PAK while offering a 66 % lower height. Due to its top-side cooling, the package claims a delivery of excellent thermal capability, with an extremely low junction to case (drain) thermal resistance of 0.25 °C/W. This allows for 46 % higher current than the D?PAK at the same on-resistance level, enabling dramatically higher power density. In addition, the package’s gullwing leads provide excellent temperature cycle capability. Built on Vishay’s latest energy-efficient E Series superjunction technology, the SiHR080N60E features low typical on-resistance of 0.074 Ω at 10 V and ultra low gate charge down to 42 nC. The resulting FOM is potentially an industry-low 3.1 Ω*nC, which translates into reduced conduction and switching losses to save energy and increase efficiency in power systems > 2 kW. For improved switching performance in hard-switched topologies such as PFC, half-bridge, and twoswitch forward designs, the MOSFET released today provides low typical effective output capacitances Co(er) and Co(tr) of 79 pF and 499 pF, respectively. The package also provides a Kelvin connection for improved switching efficiency. The device is RoHS-compliant and halogen-free, and it is designed to withstand overvoltage transients in avalanche mode with guaranteed limits through 100 % UIS testing.

The company claims that the TLE9140 is tailored for automotive motor control applications featuring higher voltage requirements from 24 V up to a maximum of 72 V, where higher system reliability and faster switching behavior are necessary. Also claimed as an ideal complement to Infineon’s MOTIX MCU TLE987x and TLE989x 32-bit motor control SoC solutions but also suitable as 48 V BLDC driver with common MCUs on the market. Typical applications include pumps and fans, windshield wipers, the HVAC module, or e-compressors. In addition, the TLE9140 is applied as 3phase motor gate driver for applications in commercial, construction, and agricultural vehicles as well as in light electric vehicles such as eBikes, eScooters or eMotorcycles. Our new motor gate driver IC allows customers to easily scale their existing 12 V MOTIX TLE987x and TLE989x motor control designs to 24 V or 48 V systems”, says Andreas Doll, Senior Vice President, and General Manager Smart Power at Infineon. “The TLE9140EQW enables the reuse of hardware and software designs, allowing our customers to shorten their time-to-market and optimize their development costs when moving to 24/48 V systems.” they go on to say that the gate driver IC offers functional safety according to ISO 26262 ASIL B. It is housed in a small TS-DSO-32 package. The IC offers a high voltage capability up to 110 V, a gate driver capability of ~230 nC/MOSFET up to 20 kHz as well as SPI communication. It has an active lowside (LS) freewheeling function during V SM overvoltage (OV) and a wide range of important diagnostic and protection functions such as timeoutwatchdog, drain-source monitoring, overvoltage, undervoltage, cross-current and over-temperature protection as well as off-state diagnostics. In addition, the TLE9140 includes Infineon’s patented gate shaping function, an adaptive MOSFET control that can compensate for fluctuations in the MOSFET parameters in the system. It automatically adjusts the gate current to achieve the desired switching behavior. This allows the system to be optimized in terms of electromagnetic emissions (EMI) by slower slew rates, while minimizing power dissipation through shorter dead times and shorter rise/fall times.

Rated at up to 800W and 1000W, these very compact products also claim the feature of a variable speed fan with typically 30 - 42dBA audible noise. The power supplies can be used in a wide range of applications, including medical, dental, test and measurement, broadcast and industrial equipment. The series claims to accept an 85 to 265Vac input, delivering full power at 90Vac, and is available with 12V, 24V, 36V and 48V outputs. A 5V 2A standby voltage, remote on/off, remote sense and a power good signal are fitted as standard. With efficiencies of up to 95.5%, internal heating is reduced, allowing reliable operation in the compact package size. The off-load power consumption is typically <0.6W when the supply is put into standby mode. These CUS-M models can operate in -20oC to 70oC ambient temperatures, derating linearly from 40oC to 60% load at 70oC. The CUS800M and CUS1000M claim to have an input to output isolation of 4000Vac (2 x MoPP), an input to ground isolation of 2000Vac (1 x MoPP), and an output to ground isolation of 1500Vac (1 x MoPP) for B and BF rated medical equipment. The leakage current is <250µA and the maximum operating, transportation and storage altitude is 5000m. Safety certifications include IEC/EN/ES 60601-1 and IEC/EN/UL 62368-1 with CE/UKCA marking for the Low Voltage, EMC and RoHS Directives. The units also comply with EN 55011-B and EN 55032-B conducted and radiated emissions, and meet the EN 61000-3-2 harmonics, IEC60601-1-2 Edition 4 and IEC 61000-4 immunity standards.
