Quad High Side and Octal Low
MC33888FB
Side Switch for Automotive
This QHSOLSS is a single packaged combination of four discrete high-side
FETs and an integrated IC consisting of eight low-side drivers with appropriate
control, protection, and diagnostic features. The high-side drivers are useful for
both internal and external vehicle lighting applications as well as capable of
driving inductive solenoid loads. The low-side drivers are capable of controlling
low current on/off type inductive loads, such as relays and solenoids as well as
LED indicators and small lamps. The device will be useful in body control,
instrumentation, and other high power switching applications and systems.
