The onsemi FAN7888MX is a three-phase half-bridge gate driver IC designed for BLDC and PMSM motor drive applications. Housed in an SOIC-28 package, it provides three high-side and three low-side gate drivers with built-in dead time, shoot-through prevention, undervoltage lockout (UVLO), and bootstrap diode functionality. The device operates from a single 15V supply and supports logic-level input interface from MCUs.<\/p>\n

The device integrates three high-side and three low-side gate drivers in a single SOIC-28 package, providing a compact solution for three-phase inverter stages. Built-in dead time of 270 ns typical and shoot-through prevention logic ensure safe operation by preventing simultaneous conduction of high-side and low-side switches. Each channel features independent undervoltage lockout (UVLO) protection, monitoring both VDD and bootstrap voltages. Integrated bootstrap diodes simplify PCB layout by eliminating the need for external bootstrap components. The device accepts logic-level inputs from an MCU and provides 250 mA source \/ 500 mA sink drive capability, suitable for driving a wide range of power MOSFETs or IGBTs.","working_principle":"The FAN7888MX operates as a three-phase half-bridge gate driver. Each phase has a high-side driver (HO) and a low-side driver (LO), controlled by HIN and LIN logic inputs from the MCU. The high-side drivers are powered by bootstrap capacitors charged through internal bootstrap diodes when the low-side switch is on. When the high-side input (HIN) goes high, the high-side driver turns on the high-side MOSFET, pulling the phase output to the DC bus voltage. The shoot-through prevention circuit monitors both HIN and LIN \u2014 if both are high simultaneously, the device enforces dead time before allowing the complementary switch to turn on. The UVLO circuit independently monitors VDD and each bootstrap voltage, disabling the corresponding driver if the voltage falls below the threshold. The FAULT output signals any UVLO or over-temperature condition to the MCU.","pin_description":"\n
