{"product_id":"ignition-coil-driver","title":"Ignition Coil Driver","description":"\u003cp\u003eThe project presented here is an \u003cstrong\u003eIgnition coil driver\u003c\/strong\u003e featuring \u003cstrong\u003eFAN1100-F085\u003c\/strong\u003e ignition gate driver chip and IGBT. Chip is designed to directly drive an ignition \u003cstrong\u003eIGBT\u003c\/strong\u003e and control the current and spark event of the coil. The coil current is controlled via the input signal pin. When the input is driven high, the output of the chip is enabled to turn on the IGBT and start charging the coil. Output sink current is programable using resistor R5 (R\u003csub\u003eA\u003c\/sub\u003e). An input spike filter suppresses input signals of less than 13uS in duration. A Max Dwell timer is included in the chip which will turn off the IGBT if input stays active for longer than the programmable time. This time interval can be modified through an external capacitor on the C\u003csub\u003eSSD\u003c\/sub\u003e pin. When the Max Dwell timer is exceeded, the CHIP will enter a Soft-Shut-Down mode (SSD) slowly dropping the collector current by lowering the gate drive to the IGBT thereby discharging the coil such as to inhibit a spark event. Once the soft shutdown operation has started, any transition on the input signal is ignored until after the completion of the soft shutdown function. Chip also limits the collector current of the IGBT during charging. This is done through the sense resistor R6 in the emitter leg of the ignition IGBT developing a signal input to the V-Sense pin of the chip.\u003c\/p\u003e\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003ePower Supply 12V to 14V DC\u003c\/li\u003e\n\u003cli\u003eInput Frequency 5Hz-60Hz (Max 200hz)\u003c\/li\u003e\n\u003cli\u003eInput Signal 5V Type (Max 6V)\u003c\/li\u003e\n\u003cli\u003eSignal Line Input Buffer\u003c\/li\u003e\n\u003cli\u003eInput Spike Filter\u003c\/li\u003e\n\u003cli\u003eOperation from Ignition or Battery Line\u003c\/li\u003e\n\u003cli\u003eGround Shift Tolerance ±1.5 V\u003c\/li\u003e\n\u003cli\u003eProgrammable Maximum Dwell Time\u003c\/li\u003e\n\u003cli\u003eProgrammable Input Pull Down Current\u003c\/li\u003e\n\u003cli\u003eControl IGBT Current Limiting through V\u003csub\u003eSENSE\u003c\/sub\u003e Pin\u003c\/li\u003e\n\u003cli\u003eSoft Shutdown following Max Dwell Time Out\u003c\/li\u003e\n\u003cli\u003eOn Board Power LED\u003c\/li\u003e\n\u003cli\u003eScrew Terminals for Power Input and Ignition Coil\u003c\/li\u003e\n\u003cli\u003eHeader Connector for Signal Input\u003c\/li\u003e\n\u003cli\u003e4 x 4 mm PCB Mounting Holes\u003c\/li\u003e\n\u003cli\u003ePCB Dimensions 45.09 x 32.39 mm\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eConnections\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eCN1 Power Input: Pin 1 = Pin 1 +12V to 14V DC, Pin 2 = GND\u003c\/li\u003e\n\u003cli\u003eCN2 Ignition Coil: Pin 1 = + Coil, Pin 2 = -Coil\u003c\/li\u003e\n\u003cli\u003eCN3 Signal Input: Pin 1 = VCC No Use, Pin 2 = GND, Pin 3 = GND, Pin 4 = Signal Input (TTL)\u003c\/li\u003e\n\u003cli\u003eD1: Power LED\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e \u003c\/p\u003e","brand":"dotfry","offers":[{"title":"Default Title","offer_id":47249245274284,"sku":"G190","price":14.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0757\/6436\/7532\/files\/G190.jpg?v=1789892448","url":"https:\/\/dotfry.com\/products\/ignition-coil-driver","provider":"dotfry","version":"1.0","type":"link"}
