Infineon Technologies TLE9210x Multi-MOSFET Drivers
Infineon Technologies TLE9210x Multi-MOSFET Drivers are designed to control up to eight half-bridges (up to 16 N-Channel MOSFETs) in one package. This series is ideal for applications that involve automotive DC motor and solenoid control, such as power seat modules, power closure systems, and more. Configuration of these drivers is enabled through a 24-bit serial parallel interface (SPI) to control the half-bridges. The SPI offers a wide range of diagnostic features, including monitoring the supply voltage, charge pump voltage, temperature warning, and overtemperature shutdown. Each gate driver monitors its external MOSFET drain-source voltage for hard-short circuit conditions. This is while the TLE9210x drivers are observing the current passing through the integrated op amps, providing configurable soft-short circuit detection.Infineon Technologies TLE9210x Multi-MOSFET Drivers come housed in a VQFN-48 package with an exposed pad, which supports optical lead tip inspection while offering optimal thermal performance and minimizing the required PCB space.
