One cylinder small engine control IC

33813

solution for managing one-cylinder engines. With five drivers, two 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.

ONE CYLINDER SMALL ENGINE

CONTROL IC

Features:

• Operates over supply voltage range of 4.5 V < V_PWR< 36 V

• Start-up/shut-down control and power sequence logic with KEYSW input

• MCU supply: V_CCis a 5.0 V ( 2.0%, 200 mA) regulated supply

• Sensor supply: V_PROT(100 mA) is a V_CCtracking protected sensor supply

• Two configurable pre-drivers for IGBT or general purpose gate MOSFETs for

ignition and O₂sensor (HEGO) heater:

48-PIN LQFP-EP

• PWM

• Overcurrent shutdown

• Short-to-battery shutdown

Applications:

• Five low-side drivers with full diagnostics, self-protection and PWM control:

• One fuel injector drivers, R_DS(on)= 0.6 Ω, I_LIMIT= 1.8 A, to drive typical 12 Ω

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, R_DS(on)= 0.4 Ω, I_LIMIT= 3.0 A, to drive fuel pump

• Relay 2 driver, R_DS(on)= 1.5 Ω, I_LIMIT= 1.2 A, to drive power relay

• Lamp driver, R_DS(on)= 1.5 Ω, I_LIMIT= 1.2 A, to drive warning lamp or an LED

• Programmable Tachometer Driver, R_DS(on)= 20 Ω, I_shutdown= 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
