Data sheet: Technical Data  
Two cylinder small engine control IC  
33814  
Powered by SMARTMOS technology, the 33814 delivers a cost-optimized IC  
solution for managing one and two-cylinder engines. With six drivers, three pre-  
drivers, a 5.0 V regulator for the MCU, a protected external sensor supply, and a  
high level of integration, the IC offers an ideal response to contemporary market  
requirements. The innovative VRS system optimizes noise immunity under  
cranking conditions. Diagnostic and protection features present on all outputs allow  
applications to operate with greater safety.  
TWO CYLINDER SMALL ENGINE  
CONTROL IC  
Features:  
• Operates over supply voltage range of 4.5 V < VPWR < 36 V  
• Start-up/shut-down control and power sequence logic with KEYSW input  
• MCU supply: VCC is a 5.0 V ( 2.0%, 200 mA) regulated supply  
• Sensor supply: VPROT (100 mA) is a VCC tracking protected sensor supply  
• Three configurable pre-drivers for IGBT or general purpose gate MOSFETs for  
ignition and O2 sensor (HEGO) heater:  
98ASA00737D  
AE SUFFIX (PB-FREE)  
48-PIN LQFP-EP  
• PWM  
• Overcurrent shutdown  
• Short-to-battery shutdown  
Applications:  
• Six low-side drivers with full diagnostics, self-protection and PWM control:  
• Two fuel injector drivers, RDS(on) = 0.6 Ω, ILIMIT = 1.8 A, to drive typical 12 ꢀ  
high-impedance injectors  
Small Engine Control for:  
• Motor scooters  
• Small motorcycles  
• Lawn mowers  
• Lawn trimmers  
• Snow blowers  
• Chain saws  
• Gasoline-driven electrical generators  
• Outboard motors  
• Relay 1 driver, RDS(on) = 0.4 ꢀ, ILIMIT = 3.0 A, to drive fuel pump  
• Relay 2 driver, RDS(on) = 1.5 ꢀ, ILIMIT = 1.2 A, to drive power relay  
• Lamp driver, RDS(on) = 1.5 ꢀ, ILIMIT = 1.2 A, to drive warning lamp or an LED  
• Programmable Tachometer Driver, RDS(on) = 20 ꢀ, Ishutdown = 60 mA, to drive  
a Tachometer display  
• Innovative configurable VRS conditioning circuit, with two different parameter  
settings for engine cranking and running mode and an optional automatic mode  
to improve noise immunity in cranking conditions  
• K-line (ISO9141)  
• MCU reset generator and programmable watchdog  
• MCU Interface: 16-bit SPI and parallel interface with 5.0 V IO capability
