 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.
