 Description
The DIA58108 is a multi-channel NMOS gate driver
which can drive up to 16 MOSFETs. The devices
can be used as 8ch half-bridges for driving DC motor
control applications, and they can also be used as
high-side or low-side drivers for wider automotive
applications.
EMC performance can be well tuned by adjustable
slew rate with independence from cross-current
protection time and turn on/off delays. The on-board
measurement and self-adaption of external
MOSFET switching times allow balancing of power
dissipation and EMC performance.
The DIA58108 integrates complete diagnostics and
protections, where brake protection greatly
enhances system reliability. This function allows the
motor to enter permanent brake mode to avoid
unintended movement of the motor. It can also
protect against supply overvoltage caused by the
motor working in generator mode to protect the
system. The 24-bit SPI interface allows more flexible
device configuration and fault observability.
For A version, DIA58108 can separately configure
the drain-source overvoltage threshold for the
high-side and low-side MOSFETs of a half bridge,
and it can also support the independent control
mode which is friendly for high-side switch
application.
