Description

The UC1724 family of Isolated Drive Transmitters, along with the UC1725 solated Drivers, provide a unique solution to driving isolated power OSFET gates. They are particularly suited to drive the high-side devices n a high-voltage H-bridge. The UC1724 devices transmit drive logic, and rive power, to the isolated gate circuit using a low cost pulse transformer.

This drive system utilizes a duty-cycle modulation technique that gives instantaneous esponse to the drive control transistions, and reliably passes teady-state, or DC, conditions. High frequency operation, up to 600kHz, llows the cost and size of the coupling transformer to be minimized.

These devices UC1724 will operate over an 8 to 35 Volt supply range. The dual high urrent totem pole outputs are disabled by an uder-voltage lockout circuit to revent spurious responses during startup or low voltage conditions.

These devices UC1724 are available in 8 pin plastic or ceramic dual-inline packages, aswell as 16 pin SOIC package.
