Product Preview  
One Cylinder Small Engine  
Control IC  
33813  
ONE CYLINDER SMALL ENGINE  
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 a Serial Peripheral  
Interface (SPI). The five low side drivers are intended for driving a fuel  
injector, a lamp, two relays or other loads, and a tachometer. The pre-  
driver is intended to drive IGBT or MOSFET transistors to control ignition  
coils, and/or a HEGO heater. The device is packaged in a 48 pin LQFP-  
EP with an exposed pad.  
CONTROL IC  
98ASA00173D  
AE SUFFIX (PB-FREE)  
48-PIN LQFP-EP  
Features:  
• Operates over a supply voltage range of 4.5 V VPWR 36 V  
• Logic stability guaranteed down to 2.5 V  
• One fuel injector driver - typical of 1.3 A  
Applications  
• One ignition IGBT or general purpose gate pre-driver  
Small Engine Control for:  
• One O2 sensor (HEGO) heater general purpose gate pre-driver  
• Relay 1 driver, typically 2.0 A, can be used for fuel pump control  
• Relay 2 driver, typically 1.0 A, can be used as power relay control  
• Lamp driver, typically 1.0 A can also be used to drive an LED  
• VPROT protected sensor supply tracks VCC +5.0 V regulator  
• MCU reset generator -system integrity monitor (watchdog)  
• VPP pre-regulator provides power for VCC and VPROT regulators  
• Independent fault protection with all faults reported via the SPI  
• ISO 9141 K-line interface for communicating diagnostic messages  
• Start-up / shut-down control and power sequence logic  
• Interfaces directly to MCU using a 5.0 V SPI and logic I/O  
• Differential / single-ended VRS conditioning circuit with auto/manual  
selected thresholds and filter times with digital and tachometer outputs  
• Lawn Mowers  
• Motor Scooters  
• Small Motorcycles  
• Lawn Trimmers  
• Snow Blowers  
• Chain Saws  
• Gasoline-driven Electrical Generators  
• Outboard Motors
