TECHNICAL DATA
Powerful High-grade FET driver
IL33091A
Description of basic functions.
The capability of handling high voltages on power line attributed to
transient commutation of loads in conditions of automobile
exploitation.
Load of microcircuit is a device on the base of MOS transistors that
enables switching high current levels in automobile electrical
system. Microcircuit has Fault indication output when there is short
circuit in load or when load transistor current level exceeds preset
value.

Functions
Microcircuit provides pumping of charge (on output capacity on pin Gate of gate control)to drive
power MOS transistor. Input Input , compatible with logic levels of CMOS microcircuits ,controls
pumping of charge (switch in/switch off).
Check of drain-source voltage is implemented (VDS) on power МОS transistor, detection of
shorted load , presentation of error signal on pin Fault.
Microcircuit has pin VT of timer, that is both input in timer window comparators and output of
current square circuit, depending on r m s voltage drain-source on power MOS transistor, as power
dissipated in МОS device is proportional to VDS2.
External resistor RT and capacitor CT, connected to timer pin enable programming of timing data
necessary for protection of power MOS-device.
Internal circuit of stabilizer diodes with the total break down voltage of about 30V provides
protection of microcircuit and power МОS transistor from supply voltage value to be exceeded.
Activation of microcircuit Zener stabilizer diodes attributed to switching-off МОS transistor for the
time when supply voltage value exceeded , in addition pin Fault does not change its logic state .

* Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device.
These are stress ratings only and functional operation of the device at these or any other conditions beyond those
indicated under “recommended operating conditions” is not implied.
Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
