NCV7608
Octal Configurable
Low/High Side Driver
The NCV7608 integrates 8 output drivers configurable in any
combination of high−side, low−side, or H−Bridge configurations. The
integrated standard Serial Peripheral Interface (SPI) allows digital
control of all output stages and provides diagnostic fault information.
In addition, four channels (#5−8) can be PWM controlled via external
control input pins.
Integrated clamping circuits (both in high and low−side operational
modes), waveshaping, positive and negative transient protection, and
dedicated channel pair overtemperature shutdown circuits provide for
a wide range of automotive and industrial applications.
