FAN3278 30V PMOS-NMOS Bridge Driver The onsemi FAN3278, a dual 1.5A gate driver is optimized to drive a high-side P-channel MOSFET and a low-side N-channel MOSFET in motor control applications operating from a voltage rail up to 27V. This onsemi bridge driver has TTL input thresholds and provides buffer and level translation from logic inputs. The FAN3278's internal circuitry prevents the output switching devices from operating if the VDD supply voltage is below the IC operation level. Internal 100kΩ resistors bias the non-inverting output LOW and the inverting output to VDD to keep the external MOSFETs off during startup intervals when logic control signals may not be present.
