L9857-TR Overview
The 8-SOIC (0.154, 3.90mm Width) package offers greater flexibility.A package of Tape & Reel (TR) has been used.Gate drivers incorporates wGate driversh 1 drivers for Gate driverss configuration.Surface Mount is the way in which it is mounted.In the absence of a power supply voltage of 10V~18V V, it is able to demonstrate its superiority.A gate type of N-Channel MOSFET has been used in its design.The allowable temperature range that this device can be operated in is -55°C~150°C TJ.Non-Inverting is used as the input type.There are 8 terminations to form the base of its configuration.Numerous related parts are available for its base part number L9857.The mount method is Surface Mount.The pins are configured with 8 when designing the chip.Specification is for 15V supply voltage operation.HALF BRIDGE BASED PERIPHERAL DRIVER is employed as its interface IC.There is an output current limit of 500mA for this device.Several electronic components are included in its subcategory of Peripheral Drivers.A board with 8 component pins is available.Ideally, the high-side voltage should not exceed 300V.To maintain higher stability, the supply current should always be 400μA.Mosfet gate drivers is recommended that you set the operating supply voltage to 17V.When 200kHz is used frequently, efficiency can be improved.
