Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

Shenzhen Mingjiaoda Electronics Co., Ltd. imports and supplies Infineon motor control IC TLE92108-232QX multiplexed MOSFET drivers are ideally suited for applications involving automotive DC motor and solenoid control, such as power seat modules, power closure systems, and more.

Device Overview

The TLE92108-232QX is a multi MOSFET driver IC designed to control up to sixteen n-channel MOSFETs. it includes eight half-bridges for use in 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 TLE92108-232QX and control the half-bridges. It also allows the status register to be read for diagnostics.

The TLE92108-232QX provides a variety of diagnostic functions such as monitoring supply voltage, charge pump voltage, temperature warning, and overtemperature shutdown. Each gate driver can independently monitor its external MOSFET drain-source voltage for fault conditions.

The TLE92108-232QX multi MOSFET driver is available in a VQFN-48 package with exposed pads to support optical lead termination detection while providing optimal thermal performance and minimising required PCB space.
