Fairchild’s high-voltage process and common-mode noise canceling technique provide stable operation of high-side drivers under high-dv/dt noise circumstances. An advanced level-shift circuit allows high-side gate driver operation up to VS = -9.8V typical for VBS =15V. The protection functions include under-voltage lockout and inverter over-current trip with an automatic faultclear function. Over-current protection that terminates all six outputs can be derived from an external current-sense resistor. An open-drain fault signal is provided to indicate that an over-current or under-voltage shutdown has occurred. The UVLO circuits prevent malfunction when VDD and VBS are lower than the specified threshold voltage. Output drivers typically source and sink 350mA and 650mA, respectively which is suitable for three-phase half-bridge applications in motor drive systems. 24-SOIC Ordering Information Package Operating Temperature FAN7389M 1 FAN7389MX 1 24-SOP -40 to +125°C Note These devices passed wave soldering test by JESD22A-111.
