One Cylinder Small Engine Control IC
33813
The 33813 is an engine control analog power IC intended for one cylinder motorcycle and other small engine control applications.
The IC consists of five integrated low side drivers, two pre-drivers, a Variable Reluctance Sensor (VRS) input circuit, a voltage pre-
regulator using an external pass
transistor, and two 5.
0 volt internal
regulators, one for the microcontroller unit (MCU) VCC supply and the other for use as a protected sensor supply.
Also included is an MCU reset control circuit with watchdog, an ISO 9141 K-line interface for diagnostic communication and...
