Description:Max rDS(on) = 4.5 mΩ at VGS = 10 V, ID = 18.5 A; RoHS compliant ; High performance trench technology for extremely low rDS(on) ; HBM ESD protection level of 5.6kV typical (note 3) ; High power and current handling capability ; Max rDS(on) = 6.0 mΩ at VGS = 4.5 V, ID = 16 A
The FDS8813NZ can operate from -40°C to 150°C, making it suitable for high-reliability applications.
To ensure proper biasing, connect the VCC pin to a stable 5V supply, and the VBS pin to a stable 12V supply. Also, ensure the input voltage (VIN) is within the recommended range of 4.5V to 18V.
To minimize EMI and thermal issues, use a multi-layer PCB with a solid ground plane, keep the input and output traces short and separate, and use thermal vias to dissipate heat. Also, place the device near a heat sink or a thermal pad.
Use a voltage regulator or a voltage limiter to prevent overvoltage conditions. For overcurrent protection, use a current sense resistor and a comparator to detect excessive current, and then shut down the device or trigger an alarm.
A bootstrap gate drive circuit is recommended, which uses a capacitor to store energy and a diode to isolate the gate drive from the power supply. This ensures proper gate voltage and minimizes power losses.
