Datasheet summary Rev. 1.0 www.infineon.com 1 2019-08-29 TLE92108-231QX Multiple MOSFET Driver IC Overview Description The TLE92108-231QX is a Multi-MOSFET driver IC dedicated to control up to sixteen n-channel MOSFETs. It includes eight half-bridges for DC motor control applications such as automotive power seat control or other applications. A 24-bit Serial Peripheral Interface (SPI) is used to configure the TLE92108-231QX and to control the half- bridges. It also allows the read out of the status registers for diagnostic purpose. The TLE92108-231QX offers a wide range of diagnostic features such as the monitoring of the supply voltage, the charge pump voltage, temperature warning and over-temperature shutdown. Each gate driver monitors independently its external MOSFET drain-source voltage for fault conditions. The device is housed in a VQFN-48 with exposed pad supporting lead tip inspection. The package provides a good thermal performance and minimizes the required PCB space. Type Package Marking TLE92108-231QX PG-VQFN-48 TLE92108-231QX Datasheet summary 2 Rev. 1.0 2019-08-29
