ISL89160, ISL89161, ISL89162
The ISL89160, ISL89162, and ISL89162 are high-speed, 6A,
dual channel MOSFET drivers. These parts are identical to the
ISL89163, ISL89164, ISL89165 drivers but without the enable
inputs for each channel.
Two input logic thresholds are available: 3.3V (CMOS and TTL
compatible) and 5.0V (CMOS).
Precision thresholds on all logic inputs allow the use of external
RC circuits to generate accurate and stable time delays on both
inputs, INA and INB. This capability is very useful for dead time
control.
At high switching frequencies, these MOSFET drivers use very
little bias current. Separate, non-overlapping drive circuits are
used to drive each CMOS output FET to prevent shoot-thru
currents in the output stage.
The undervoltage lock-out (UV) insures that driver outputs remain
off (low) until VDD is sufficiently high for correct logic control.
This prevents unexpected behavior when V_DD is being turned on
or turned off.
