Isolated High Side IGBT Driver  
FEATURES  
DESCRIPTION  
The UC1727 and its companion chip, the UC1726, provide all the  
necessary features to drive an isolated IGBT transistor from a TTL in-  
put signal. A unique modulation scheme is used to transmit both  
power and signal across an isolation boundary with a minimum of ex-  
ternal components.  
Receives Power and Signal from Single  
Isolation Transformer  
Generates Split Rail for 4A Peak Bipolar  
Gate Drive  
16V High Level Gate Drive  
Protection features include under voltage lockout and desaturation  
detection. High level gate drive signals are typically 16V. Intermediate  
high drive levels can be programmed for various periods of time to  
limit surge current at turn on and in the event of desaturation due to a  
short circuit.  
Low Level Gate Drive more Negative  
than -5V  
Undervoltage Lockout  
Desaturation Detection and Fault  
Processing  
The chip generates a bipolar supply so that the gate can be driven to  
a negative voltage insuring the IGBT remains off in the presence of  
high common mode slew rates.  
Separate Output Enable Input  
Uses include isolated off-line full bridge and half bridge drives for mo-  
tors, switches, and any other load requiring full electrical isolation.

Soft Turn On
