Single half-bridge ICs save board space, halve on-resistance
The manufacturer promises a high level of user-friendliness, advanced protection measures and high scalability for the MotixBTN99xx product family. According to Infineon, this makes the product series ideal for a wide range of automotive applications, examples being seat controls, electric tailgates and electrically operated sliding doors. In addition, the integration of functions in a single rugged package makes the ICs generally suitable for applications where a small footprint on the PCB is critical.
“MotixBTN89xx (NovalithIC) is a well-known and very successful product family on the market. Since 2015, we have already shipped more than 500 million units to automotive customers worldwide,” said Andreas Doll, senior vice president and general manager automotive body power at Infineon. “Our new BTN99xx family is available in a small HSOF-7 package and offers a space saving of 60 percent compared to the previous generation.”
Infineon’s advanced chip-by-chip and chip-on-chip assembly technology enabled the new devices to be realised in a robust package. Using the latest MOSFET technologies under applications of this manufacturer’s innovative chip thinning process, the typical path resistance for the BTN99xx family has been reduced by 47 per cent to 5.30 mΩ at 25°C, while increasing the current limit to 75 A. As a result, this family offers a unique and cost-effective solution for motor control with high-current pulse-width modulation while requiring very little space on the PCB.
The MotixBTN99xx complements Infineon’s current portfolio of Motix motor control ICs, which is positioned between discrete gate drivers and highly integrated embedded power motor control products with arm processors. The BTN99xx family consists of two product variants, the BTN9970LV and the BTN9990LV, both housed in a 7 x 8 mm² HSOF-7 package.
The BTN9970LV is already released for production, the BTN9990LV will be launched in February 2022.
