MOTIX™ multi MOSFET gate driver ICs from Infineon
The MOTIX™ TLE9210x is a family of multi MOSFET gate driver ICs, designed to control up to eight half-bridges (up to 16 n-channel MOSFETs) with one packaged device. A 24-bit Serial Parallel Interface (SPI) enables configuration of the MOTIX™ TLE9210x and is used to control the half-bridges. The SPI offers a wide range of diagnostic features such as the monitoring of the supply voltage, the charge pump voltage, temperature warning and overtemperature shutdown. Each gate driver monitors its external MOSFET drain source voltage for hard-short circuit conditions, while the devices can observe the current passing through the integrated current sense amplifier providing configurable soft-short circuit detection, in both cases providing active latching hardware protection independent of any software measures. The device is housed in a VQFN-48 with exposed pad, which supports optical lead tip inspection while providing optimal thermal performance and minimizing the required PCB space.
MOTIX™ TLE9210x series is an easier, smaller & more cost-efficient way to drive multiple half-bridges in DC motor control applications.
Benefits and highlights of multiple half-bridge driver ICs
- Enable cost and board space improvements – The MOTIX™ TLE9210x allows driving up to 8 half-bridges with one single driver IC, providing a very cost-effective solution on system level. Having only one driver device for several half-bridges enables further savings, such as less pick & place costs as well as less required PCB space compared to competing (discrete) solutions.
- Adaptive driver capability – Multi-stage slew rate control enables EMC tuning via SPI, including adjusting slew rate with independence from dead-time and turn on/off delays. The on-board measurement and self-adaption of external MOSFET switching times allows balancing of power dissipation vs. EMC performance, adjusts for MOSFET lot-to-lot variations.
- Motor brake mode – all variants are pin and software compatible. The MOTIX™ TLE9210x-232QX versions offer in addition a unique protection feature even in sleep mode. It can be configured as a permanent motor brake to avoid unintended movement of the motor. The motor brake can also be configured to be activated in case of supply overvoltage caused by motor working in generator mode to protect the system.
Introduction training to Adaptive MOSFET Control
Multi MOSFET gate driver ICs in automotive applications
The Infineon devices are optimized but not limited for automotive applications, with advanced protection and diagnostic features. ‒Target applications include, seat motor control, closure systems as power lift gate control or sliding doors, various control of loads in a body control module with only one device. For example, centralized door lock control, window lift, wiper, washer pumps to name a few.
Our reference design describes a detailed implementation of a central door lock application, where the control of all lock motors occurs from a central location such as from a body control module. It is shown how proper protection and diagnosis of external MOSFETs is ensured in combination with OptiMOS™-6 half-bridge MOSFETs and Traveo™ II CYT4BF series microcontroller, which is especially designed for body control modules.

What is the adaptive MOSFET control feature?
With the use of our patented concept of adaptive MOSFET control - a multi-stage slew rate control enables EMC optimization via SPI, including adjusting slew rate with independence from dead-time and turn on/off delays. The on-board measurement and self-adaption of external MOSFET switching times allows balancing of power dissipation vs. EMC performance, adjusts for MOSFET lot-to-lot variations and reduces the need of end-of-line effort.

Infineon's Multi-MOSFET Driver ICs are optimized for automotive comfort motor control applications. Semiconductor solutions are getting more and more attractive to replace relay based solutions in automotive motor control. Increasing numbers of motors and increasing pressure on saving space, weight and costs accelerate the trend. Furthermore semiconductors lever benefits such as diagnostic feedback, higher efficiency, longer life time, higher precision, fast switching and programmability. Seat as one example of comfort applications requires a smooth movement of the seat and the passenger, what can be realized by PWM with ICs.
The PWM capable devices of the TLE9210x product family offer moreover an integrated slew rate regulation via SW to overcome the challenge of increased EMC caused by common PWM. The high integration factor of the device and scalability within the family allows high flexibility in changing numbers of motors in a seat application to use one design only for several platforms, no matter if low level equipped power seats or high level with e.g. 11 motors controlled from one ECU.
Infineon provides a broad portfolio for comfort applications as power lift gate and other closure systems (sliding doors, tailgate or power roof). In case of the TLE9210x family Infineon offers a dedicated product variant with an integrated motor brake mode. This is an advanced feature to prevent system damage by manual closure, what is a fundamental challenge for closure applications. The motor brake is configurable and usable in sleep mode without compromising the outstanding low sleep current of these devices. The regulated slew rates via SW realize an optimized EMC behavior during PWM independent of the MOSFET variation. Use TLE92104 for driving 2 lifting motors or extend to TLE92108 and drive additional motors as cinching latch or different functions of the trunk zone.
