ISL83204A
FN6397.2
60V/2.5A Peak, High Frequency Full Bridge
FET Driver
The ISL83204A is a high frequency, medium voltage Full
Bridge N-Channel FET driver IC, available in 20 lead plastic
SOIC and DIP packages. The ISL83204A includes an input
comparator used to facilitate the “hysteresis” and PWM
modes of operation. Its HEN (high enable) lead can force
current to freewheel in the bottom two external power
MOSFETs, maintaining the upper power MOSFETs off.
Since it can switch at frequencies up to 1MHz, the
ISL83204A is well suited for driving Voice Coil Motors,
switching power amplifiers and power supplies.
ISL83204A can also drive medium voltage brush motors,
and two ISL83204As can be used to drive high performance
stepper motors, since the short minimum “on-time” can
provide fine micro-stepping capability.
Short propagation delays of approximately 55ns maximize
control loop crossover frequencies and dead-times which
can be adjusted to near zero to minimize distortion, resulting
in precise control of the driven load.
