The Infineon low-current DC motor bridge family consists
of a broad variety of bridges for stepper and DC brush
motors including servo motors. They are designed for
use in automotive and industrial applications. Typical
applications are light leveling, HVAC flap control, and
mirror adjustment.
The products are oered with protection features as well as
diagnosis. Depending on the product type the protection
ranges from basic protection against overtemperature to
a full set of protection against open-load, overvoltage,
undervoltage, overtemperature and short-circuit. The
diagnosis capabilities range from a simple status flag to
communication via a 16-bit SPI.
LO = Lockout
OL = Open-Load
OV = Overvoltage
UV = Undervoltage
OT = Overtemperature
SC = Short-Circuit

Stepper Motor Drivers
The TCA3727 and TLE4726 et seqq. cover a broad range of
applications from automotive to industry. The TLE4726
can be used in 24V applications. The products are either
produced in DOPL, Infineon’s robust bipolar technology, or
SPT, a technology combining bipolar CMOS and DMOS cells.
