“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 low-side (LS) freewheeling function during V SM overvoltage (OV) and a wide range of important diagnostic and protection functions such as timeout-watchdog, 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.
