MARKING DIAGRAM
The NCP51105 is a high current low side gate driver designed to
drive Power MOSFET and IGBT. The logic input is compatible with
CMOS and TTL output. The NCP51105 has OCP pin to provide over
current protection with negative voltage detected across switching
current sensing resistor and EN pin that be able to report faults status
to external controller such as MCU. EN pin must be pulled up to
higher voltage than threshold for normal operation while it will be

circuitry provides an under−voltage lockout function by holding the
output low until supply voltage is recovered into operating range and
fault recovery time can be programmable by time constant set of
resistance and capacitance connected to EN pin.
