Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

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 5.0 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 control:

• Two fuel injector drivers, RDS(on) = 0.6 Ω, ILIMIT = 1.8 A, to drive typical 12 Ω high-impedance injectors

• Relay 1 driver, RDS(on) = 0.4 Ω, ILIMIT = 3.0 A, to drive fuel pump

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

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

• Programmable Tachometer Driver, RDS(on) = 20 Ω, 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

Applications:

Small Engine Control for:

• Motor scooters

• Small motorcycles

• Lawn mowers

• Lawn trimmers

• Snow blowers

• Chain saws

• Gasoline-driven electrical generators

• Outboard motors

• 1.Is the inventory and price seen on the platform accurate?

  A: all online goods on the shelves can be ordered online, but considering the large liquidity of spot inventory, it is not possible to achieve 100% accuracy at present. In case of any abnormality, you can contact our company online and give the corresponding solution.

• 2.Are all our products genuine?

  A: our self-supporting products are from cooperative domestic and foreign original factories or authorized agents, and the source can be traced to ensure the original and authentic products.

• 3.Can you provide the qualification certificate of the original factory or agent?

  A: at present, our self-employed brands TI，ST，ADI，NXP，LATTICE，CYPRESS，INFINEON，XILINX and other first-line brands. Other channels are the original factory and agency channels. If necessary, we can communicate and confirm according to the specific brand and model.

• 4.Can I make an inquiry through the company's website?

  A: You can inquire through the website, or by phone and email.

• 5.When can I deliver the goods after placing an order? How long will it take to get there?

  A: the delivery date is marked in most commodity information. You can estimate the delivery time of the commodity according to the delivery date. The specific arrival time depends on the warehouse where the commodity is located and the logistics mode you choose.

• 6.Can the company issue an invoice?

  A: you can issue ordinary invoices for individual users or special VAT invoices for enterprise users.
