Unitrode UC1724/UC2724/UC3724 Isolated Drive Transmitter Datasheet
The UC1724 family provides a unique solution for driving isolated power MOSFET gates, particularly suited for high-side devices in H-bridge configurations. These devices transmit logic and drive power to an isolated gate circuit using a low-cost pulse transformer.
Key features include 500mA output drive capability (source or sink), programmable operating frequency up to 600kHz, and the ability to pass DC information across the isolation barrier via duty-cycle modulation. The devices operate over an 8 to 35V supply range.
