High Speed, Dual Channel, 6A, Power MOSFET
Driver with Enable Inputs
ISL89163, ISL89164, ISL89165
The ISL89163, ISL89164, and ISL89165 are high-speed,
6A, dual channel MOSFET drivers with enable inputs.
These parts are identical to the ISL89160, ISL89161,
ISL89162 drivers but with an added enable input for
each channel occupying NC pins 1 and 8 of the
ISL89160, ISL89161, ISL89162.
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 threshold 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-thru currents in the
output stage.
The under voltage lockout (UV) insures that driver
outputs remain off (low) during turn-on until VDD is
sufficiently high for correct logic control. This prevents
unexpected glitches when VDD is being turn-on or
turn-off.
