Figure 1 Block diagram
The TLE92108 APPKIT board provides a simple, easy-to-use tool to get familiar with Infineon's Multi MOSFET
Driver TLE92108-232QX (TLE92108).
It contains the TLE92108 and a typical application circuit including 8 MOSFET half-bridges to drive up to 8 DC
motors. The board is ready to be connected to a vehicle level power supply and is controlled over SPI.
All pins relevant to control the device can be accessed via the dedicated 8 × 2 header using the uIO-stick by
hitex EMBEDDED TOOLS & SOLUTIONS (http://www.hitex.com/uIO).
The board is powered by the power connector and provides an active on-board reverse-polarity protection for
fastest response time in case of reverse polarity with minimal power-loss during normal operation.
The board allows control of Phase 1-8 which can be used to control up to 8 motors independently that can be
connected to OUT1-8 with the 4 screw terminal block motor connectors.
2 high-side shunts provide load current measurement and monitoring.

Infineon's new OptiMOS™ 5 40 V product family in S3O8 package combines leading power MOSFET technology
with 3.3 × 3.3 mm2 leadless power package for very compact and robust automotive system solutions
(Datasheet of IPZ40N04S5-3R1).
Reverse polarity protection
The active reverse polarity protection is based on the design documented in the "Reverse Polarity Protection
for Embedded Power ICs" Application Note (Z864338247).
