MC33814 - NXP

MC33814 Two cylinder small engine controller

NXP Semiconductors Technical Data Document Number: MC33814 Rev. 14, 10/2020 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.

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 5.0 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:
• PWM
• Overcurrent shutdown
• Short-to-battery shutdown
• Six low-side drivers with full diagnostics, self-protection and PWM contro.
