The NCx5703y are high−current, high−performance stand−alone

IGBT drivers for high power applications that include solar inverters,

motor control and uninterruptible power supplies. The devices offer a

cost−effective solution by eliminating external output buffer. Devices

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

desaturation protection (DESAT) and Active open−drain FAULT

output. The drivers also feature an accurate 5.0 V output. The drivers

are designed to accommodate a wide voltage range of bias supplies

including unipolar and NCx5703B even bipolar voltages.

Depending on the pin configuration the devices also include Active

Miller Clamp (NCx5703A), separate high and low (VOH and VOL)

driver outputs for system design convenience (NCx5703C)

and Enable function for driver output control by external signal

(NCx5703D).

All four available pin configuration variants have 8−pin SOIC

package.
