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.

NCx5707B accommodates bipolar voltages.

Depending on the pin configuration the devices also include Active

Miller Clamp (NCx5707A) and separate high and low (VOH and VOL)

driver outputs for system design convenience (NCx5707C).

All three available pin configuration variants have 8−pin SOIC

package.
