Two cylinder small engine control IC
Powered by SMARTMOS technology, the 33814 delivers a cost-optimized IC solution for managing one and two-cylinder engines. With six drivers, three predrivers, 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.
Features:
• Operates over supply voltage range of 4.5 V < VPWR < 36 V • Start-up/shutdown control and power sequence logic with KEYSW input • MCU supply: VCC is a 5.
