MUNICH – Infineon Technologies AG in Munich is introducing the MOTIX TLE9140EQW gate driver integrated circuit for brushless DC motor control in demanding 24-to-48-volt applications.
The TLE9140 is tailored for automotive motor-control applications featuring relatively high voltage requirements from 24 volts to a maximum of 72 volts, where relatively high system reliability and faster switching behavior are necessary. Electric Bike Kit With Battery

Typical applications include pumps and fans, windshield wipers, the HVAC module, or e-compressors. In addition, the TLE9140 is applied as 3-phase motor gate driver for applications in commercial, construction, and agricultural vehicles, as well as in light electric vehicles such as eBikes, eScooters, or eMotorcycles.
The gate driver integrated circuit offers functional safety according to ISO 26262 ASIL B. It is housed in a small TS-DSO-32 package. The integrated circuit offers a high voltage capability up to 110 volts.

It has an active low-side (LS) freewheeling function during-volt 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.
To accelerate the evaluation and design-in process, Infineon's MOTIX motor control ICs are accompanied by a wide range of software and tools. The TLE9140 evaluation board is user-friendly and enables rapid evaluation and prototyping. In addition, Infineon provides a configuration wizard and a device driver for the TLE9140 that provides a simple API for generating the control frames for the external bridge driver via SPI.
