FAN7888MX

FAN7888MX is a monolithic three half-bridge gate-drive IC designed for high-voltage, high-speed driving MOSFETs and IGBTs operating up to +200V. Onsemi’s high-voltage process and common-mode noise cancelling 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 UVLO circuits prevent malfunction when VDD and VBS are lower than the specified threshold voltage. Output drivers typically source/sink 350 mA / 650 mA, respectively, which is suitable for three-phase half-bridge applications in motor drive systems. Applications include battery based motor applications (E-bike, power tool), 3-phase motor inverter driver.
