gate driver consisting of three independent, high and low
side output channels. In addition to the six inputs,
which are CMOS/TTL Compatible, for the three
corresponding high side and three low side outputs,
there are dedicated lines for FAULT, ENABLE and
RESET. Overload/Short Circuit protection is
implemented by sensing a voltage across a shunt or low
value resistor which carries load current. Upon
Overload/Short Circuit detection, all outputs are
disabled. Likewise ENABLE (EN) pin, when LOW under
abnormal operating conditions, affords soft shut down of
outputs. FAULT(FLT) signal‘s status indicates that shut
down has occurred either due to Overload/Short Circuit
in driven MOSFET/IGBT or Under Voltage on V CL.
Clearing of FAULT (FLT) signal and restoration of
normal operation ensue automatically after a
programmed delay using an RC Network wired at RST
(RESET) pin. Matched propagation delays ensure
proper operation even at very high switching
frequencies. Absence of cross conduction in output
stages removes possibility of shoot through in driven
power MOSFETs or IGBTs.
