Features
• Industry Standard Driver Replacement
The ISL89410, ISL89411, ISL89412 ICs are similar to the
EL7202, EL7212, EL7222 series but with greater VDD
ratings. These are very high speed matched dual drivers
capable of delivering peak currents of 2.0A into highly
capacitive loads. The high speed performance is achieved
by means of a proprietary “Turbo-Driver” circuit that speeds
up input stages by tapping the wider voltage swing at the
output. Improved speed and drive capability are enhanced
by matched rise and fall delay times. These matched delays
maintain the integrity of input-to-output pulse-widths to
reduce timing errors and clock skew problems. This
improved performance is accompanied by a 10-fold
reduction in supply currents over bipolar drivers, yet without
the delay time problems commonly associated with CMOS
devices. Dynamic switching losses are minimized with
non-overlapped drive techniques.

Application Guidelines
It is important to minimize inductance to the power FET by
keeping the output drive current loop as short as possible.
Also, the decoupling capacitor, Cq, should be a high quality
ceramic capacitor with a Q that should be a least 10x the
gate Q of the power FET. A ground plane under this circuit is
also recommended.

FIGURE 15. SUGGESTED CONFIGURATION FOR DRIVING
INDUCTIVE LOADS
Where high supply voltage operation is required (15V to
18V), input signals with a minimum of 3.3V input drive is
suggested and a minimum rise/fall time of 100ns. This is
recommended to minimize the internal bias current power
dissipation.
Excessive power dissipation in the driver can result when
driving highly capacitive FET gates at high frequencies.
These gate power losses are defined by Equation 1:
P = 2 • Q C • V gs • f SW
(EQ. 1)
where:
FIGURE 14. RECOMMENDED LAYOUT METHODS
In applications where it is difficult to place the driver very
close to the power FET (which may result with excessive
parasitic inductance), it then may be necessary to add an
external gate resistor to dampen the inductive ring. If this
resistor must be too large in value to be effective, then as an
alternative, Schottky diodes can be added to clamp the ring
voltage to V+ or GND.
8
P = Power
Qc = Charge of the Power FET at Vgs
Vgs = Gate drive voltage (V+)
fSW = switching Frequency
Adding a gate resistor to the output of the driver will transfer
some of the driver dissipation to the resistor. Another
possible solution is to lower the gate driver voltage which
also lowers Qc.
