FEATURES

DESCRIPTION

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 hystere-

sis 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 capaci-

tive 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.
