CK240

4-channel ignition driver for external igniters

Application & Technical Summary

Ck240

CK240 is a driver for up to four external igniters, typically located inside the ignition coil assembly at the spark plug.

Ignition driver with extensive diagnosis functions. All outputs are protected from short circuiting.

Product benefits

  • Wiring diagnosis result is provided via SPI interface
  • Individual detection for each output
  • Ignition inhibited in case of undervoltage or reset condition
  • Extensive diagnosis of connection to ignition coil: Detection of short-circuit to UBatt, short-circuit to ground or open load

Protected outputs

All ignition outputs short circut protected to GND and Ubatt
