TECHNICAL DATA
KK33091A
Powerful High-grade FET driver
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 .

Note
1 .Standards for electrical parameters of table , unless otherwise noted , are given for conditions :
7,0 V ≤ Vcc ≤ 24 V; -40°С ≤ Тa ≤125°С.
2 .Measure total consumption current on pins 02 and 05 of microcircuit (when resistor is Rx=100 kОhm, connected
to pin 02, and resistor with the value of 45 kОhm, connected to pin 06).
3 . Protection of device from short-term voltage surge on power line at the expense of internal circuit of
semiconductor stabilitrons.
4. Measure voltage relatively pin «SRC» in shorted load mode , when voltage on load approximately will make less
than 1В in НУ relatively potential «general». Mode of measurements , residual stress on load of short-circuit mode are to
be specified in the course of development basing on the reference dependence reading results for temperature range.
5 Current coefficient of timer is a constant (coefficient )of proportionality of voltage into current conversion, used to
check VDS voltage, formed on field transistor.
