UC3724 Datasheet | Unitrode

UC1724 UC2724 UC3724 Isolated Drive Transmitter Features - 500mA Output Drive, Source or Sink - 8 to 35V Operation - Transmits Logic Signal Instantly - Programmable Operating Frequency - Under-Voltage Lockout - Able To Pass DC Information Across Transformer - Up To 600kHz Operation DESCRIPTION The UC1724 family of Isolated Drive Transmitters, along with the UC1725 Isolated Drivers, provide a unique solution to driving isolated power MOSFET gates. They are particularly suited to drive the high-side devices on a high-voltage H-bridge. The UC1724 devices transmit drive logic, and drive power, to the isolated gate circuit using a low cost pulse transformer. This drive system utilizes a...
