Isolated Drive Transmitter  
FEATURES  
DESCRIPTION  
500mA Output Drive, Source or Sink  
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.  
8 to 35V Operation  
Transmits Logic Signal Instantly  
Programmable Operating Frequency  
Under-Voltage Lockout  
This drive system utilizes a duty-cycle modulation technique that gives in-  
stantaneous response to the drive control transistions, and reliably passes  
steady-state, or DC, conditions. High frequency operation, up to 600kHz,  
allows the cost and size of the coupling transformer to be minimized.  
Able To Pass DC Information Across  
Transformer  
These devices will operate over an 8 to 35 Volt supply range. The dual high  
current totem pole outputs are disabled by an uder-voltage lockout circuit to  
prevent spurious responses during startup or low voltage conditions.  
Up To 600kHz Operation  
These devices are available in 8 pin plastic or ceramic dual-inline pack-  
ages, as well as 16 pin SOIC package.
