Engine Control Integrated Circuit
The NXP MC33800 is a combination output switch and driver IC that is ideal for numerous powertrain engine control applications.
- Contains two programmable constant current drivers (CCD), an octal, low-side, serial switch (OSS) and six, external MOSFET gate pre-drivers (GD
- Overvoltage, undervoltage and thermal protection
- All drivers and switches, including the external MOSFETs, have overcurrent protection, off-state open load detection, on-state shorted load detection and fault annunciation via the SPI
- Cost effective packaging
