Product Overview

The MC33814AE is a SMARTMOS Control IC for managing one and two-cylinder engines. With six drivers, three predrivers, a 5V 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. 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.
  • Start-up/shut-down control and power sequence logic with KEYSW input
  • Sensor supply - VPROT (100mA) is a VCC tracking protected sensor supply
  • Six low-side drivers with full diagnostics, self-protection and PWM control:
  • Two fuel injector drivers
  • Relay 1 driver, RDS(on) = 0.4R, ILIMIT = 3.0A, to drive fuel pump
  • Relay 2 driver, RDS(on) = 1.5R, ILIMIT = 1.2A, to drive power relay
  • Lamp driver, RDS(on) = 1.5R, ILIMIT = 1.2A, to drive warning lamp or an LED
  • Programmable tachometer driver, RDS(on) = 20R, Ishutdown = 60mA, to drive a tachometer display
  • K-line (ISO9141)
  • MCU reset generator and programmable watchdog
  • MCU Interface - 16-bit SPI and parallel interface with 5.0V IO capability
