The NCV/NCD5705B is a high−current, high−performance

stand−alone IGBT driver for high power automotive applications that

include PTC heaters, traction inverters, high voltage DC−DC and

other auxiliary subsystems. The device offers a cost−effective

solution by eliminating external output buffer. Device’s protection

features include accurate Under−voltage−lockout (UVLO),

desaturation protection (DESAT) and Active open−drain FAULT

output. The driver also features an accurate 5.0 V output. The driver is

designed to accommodate a wide voltage range of bias supplies

including unipolar and even bipolar voltages. NCV5705B is available

in 8−pin SOIC package.
