DESCRIPTION  
FEATURES

•
750mA Output Drive, Source or Sink  
The UC1726 Isolated Drive Transmitter, and its companion chip, the  
UC1727 Isolated High Side IGBT Driver, provide a unique solution to driv-  
ing isolated power IGBTs. They are particularly suited to drive the high  
side devices on a high voltage H-bridge. The UC1726 device transmits  
the drive logic and drive power, along with transferring and receiving fault  
information with the isolated gate circuit using a low cost pulse trans-  
former.  
8 to 35V Operation  
Transmits Drive Logic and Power  
through Low Cost Transformer

•
Programmable Operating Frequency  
Up to 750kHz Operation  
This drive system utilizes a duty cycle modulation technique that gives in-  
stantaneous response to the drive control transitions, and reliably passes  
steady state, or DC conditions. High frequency operation, up to 750kHz,  
allows the cost and size of the coupling transformer to be minimized.  
Improved Output Control Algorithm  
Minimizes Output Jitter

Fault Logic Monitors Isolated High  
Side IGBT Driver UC1727 for Faults  
The UC1726 can be powered from a single VCC supply which internally  
generates a voltage reference for the logic circuitry. It can also be placed  
into a low power shutdown mode that disables the internal reference. The  
IC’s logic circuitry can be powered from an external supply, VL, to mini-  
mize overall power dissipation. Fault logic monitors the Isolated High Side  
IGBT Driver UC1727 for faults. Based on user defined timing, the  
UC1726 distinguishes valid faults, which it responds to by setting the fault  
latch pin. This also disables the gate drive information until the fault reset  
pin is toggled to a logic one.

Screens False Fault Signals

Optional External Biasing of Logic  
Circuitry can Reduce Overall Power  
Dissipation  
The UC1726 operates over an 8 to 35 volt supply range. The typical VCC  
voltage will be greater than 28 volts to be compatible with the UC1727.  
The undervoltage lockout circuitry of the Isolated High Side IGBT Driver  
UC1727 locks out the drive information during its undervoltage lockout.
