The UCC3776 is a four output BCDMOS buffer/driver designed to drive highly capacitive loads such as power MOSFET gates at high speeds. The device can be configured as either an inverting or non-inverting driver via the POL pin. The outputs are enabled by ENBL. When disabled, all outputs are active low. The device incorporates thermal shutdown with hysteresis for stability. The device also includes an undervoltage lockout circuit (UVLO) with hysteresis which disables the outputs when VDD is below a preset threshold. The outputs are held low during undervoltage lockout, even in the absence of VDD power to the device. This helps prevent MOSFET turn-on due to capacitive current through the gate-drain capacitance of the power MOSFET in the presence of high dV/dts. The logic input thresholds are compatible with standard 5V HCMOS logic.
