{"product_id":"high-current-half-bridge-with-over-current-shutdown","title":"High Current Half Bridge with Over-Current Shutdown","description":"\u003cp\u003eThis high-current half-bridge driver board is designed as a flexible, open-design platform that can be configured to meet a wide range of voltage, current, and switching-frequency requirements. The board includes an adjustable overcurrent protection circuit, allowing users to set the desired current limit by selecting an appropriate shunt resistor value and adjusting the onboard threshold trimmer.\u003c\/p\u003e\n\u003cp\u003eAn onboard current-sense shunt resistor is provided for over-current detection. Users can select the shunt resistor value according to the required current threshold. Gate resistors and optional gate-drive diodes can also be customized to optimize switching performance for specific PWM frequencies and load characteristics.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eLoad supply voltage up to 90 VDC (limited by installed DC bus capacitor ratings)\u003c\/li\u003e\n\u003cli\u003eGate driver supply voltage: 15 V nominal (10 V to 20 V operating range)\u003c\/li\u003e\n\u003cli\u003eHigh dV\/dt immunity: ±50 V\/ns over the full temperature range\u003c\/li\u003e\n\u003cli\u003e4 A source\/sink gate drive capability\u003c\/li\u003e\n\u003cli\u003eFast switching performance: 15 ns rise\/fall time with 1 nF load\u003c\/li\u003e\n\u003cli\u003eCompatible with 3 V and 5 V TTL\/CMOS logic inputs with hysteresis\u003c\/li\u003e\n\u003cli\u003eIntegrated bootstrap diode\u003c\/li\u003e\n\u003cli\u003eSmart shutdown function\u003c\/li\u003e\n\u003cli\u003eAdjustable dead time via R9\u003c\/li\u003e\n\u003cli\u003eAdjustable overcurrent protection\u003c\/li\u003e\n\u003cli\u003eInterlock function to prevent shoot-through\u003c\/li\u003e\n\u003cli\u003eComprehensive fault protection\u003c\/li\u003e\n\u003cli\u003eOn Board LED for Logic Power\u003c\/li\u003e\n\u003cli\u003eOpen-design architecture for easy customization and experimentation\u003c\/li\u003e\n\u003cli\u003e4 x 4 mmPCB Mounting Holes\u003c\/li\u003e\n\u003cli\u003ePCB Dimensions 57.15 x 46.51 mm\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eApplications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eDC motor drives\u003c\/li\u003e\n\u003cli\u003eBLDC and PMSM motor control\u003c\/li\u003e\n\u003cli\u003eHigh-power PWM switching applications\u003c\/li\u003e\n\u003cli\u003eHalf-bridge and full-bridge inverter systems\u003c\/li\u003e\n\u003cli\u003ePower electronics development and prototyping\u003c\/li\u003e\n\u003cli\u003eIndustrial and robotics control systems\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e \u003c\/p\u003e","brand":"dotfry","offers":[{"title":"Default Title","offer_id":46780264448172,"sku":"G004","price":18.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0757\/6436\/7532\/files\/003-2-768x592.jpg?v=1784282869","url":"https:\/\/dotfry.com\/products\/high-current-half-bridge-with-over-current-shutdown","provider":"dotfry","version":"1.0","type":"link"}
