- 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.
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.
