High Speed, Dual Channel, 6A, 4.5 to 16VOUT, Power
MOSFET Drivers
ISL89160, ISL89161, ISL89162
The ISL89160, ISL89161, 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 start-up sequence is design to prevent unexpected glitches
when VDD is being turned on or turned off. When VDD < ~1V, an
internal 10kΩ resistor between the output and ground helps to
keep the output voltage low. When ~1V < VDD < UV, both outputs
are driven low with very low resistance and the logic inputs are
ignored. This insures that the driven FETs are off. When
VDD > UVLO, and after a short delay, the outputs now respond to
the logic inputs.
Features
• Dual output, 6A peak currents, can be paralleled
• Typical ON-resistance <1Ω
• Specified Miller plateau drive currents
• Very low thermal impedance (θJC = 3°C/W)
• Hysteretic input logic levels for 3.3V CMOS, 5V CMOS, and TTL
• Precision threshold inputs for time delays with external RC
components
• 20ns rise and fall time driving a 10nF load.
• NC pins may be connected to ground or VDD to ease PCB
layout difficulties.
Applications
• Synchronous Rectifier (SR) driver
• Switch mode power supplies
• Motor drives, class D amplifiers, UPS, inverters
• Pulse transformer driver
• Clock/line driver

NOTES:
7. Compliance to data sheet limits is assured by one or more methods: production test, characterization and/or design.
8. This parameter is taken from the simulation models for the input FET. The actual capacitance on this input will be dominated by the PCB parasitic
capacitance.
9. A 400µs delay further inhibits the release of the output state when the UV positive going threshold is crossed. See Figure 9
10. The true state of a specific part number is defined by the input logic symbol.
11. The true state input voltage for the non-inverted inputs is greater than the Logic 1 threshold voltage. The true state input voltage for the inverted
inputs is less than the logic 0 threshold voltage.
AC Electrical Specifications VDD = 12V, GND = 0V, No Load on OUTA or OUTB, Unless Otherwise Specified. Boldface limits apply over
