CASE 751−07
NCV5705B, NCD5705B
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.
