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-sou

rce voltage is implemented (VDS) on power МОS transistor, detection of

shorted load , presentation of error signal on pin Fault.

current square circuit, depending on r m s voltage drain-source on power MOS transistor, as power

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 .
