The ISL89163, ISL89164, and ISL89165 are high-speed, 6A, dual channel MOSFET drivers with enable inputs. Precision thresholds on all logic inputs allow the use of external RC circuits to generate accurate and stable time delays on both the main channel inputs, INA and INB, and the enable inputs, ENA and ENB. The precision delays capable of these precise logic thresholds makes these parts very useful for dead-time control and synchronous rectifiers. Note that the enable and input logic inputs can be interchanged for alternate logic implementations. Three input logic thresholds are available: 3. 3V (CMOS), 5. 0V (CMOS or TTL compatible), and CMOS thresholds that are proportional to VDD. At high switching frequencies, these MOSFET drivers use very little internal bias currents. Separate, non-overlapping drive circuits are used to drive each CMOS output FET to prevent shoot-through currents in the output stage. The start-up sequence is designed to prevent unexpected glitches when VDD is being turned on or turned off. When VDDDD DD > UVLO, and after a short delay, the outputs now respond to the logic inputs.
