UC1727 UC2727 UC3727 Isolated High Side IGBT Driver FEATURES • • • • • • • • • Receives Power and Signal from Single Isolation Transformer Generates Split Rail for 4A Peak Bipolar Gate Drive 16V High Level Gate Drive Low Level Gate Drive more Negative than -5V Undervoltage Lockout Desaturation Detection and Fault Processing Separate Output Enable Input Programmable Stepped Gate Drive for Soft Turn On Programmable Stepped Gate Drive for Soft Fault DESCRIPTION The UC1727 and its companion chip, the UC1726, provide all the necessary features to drive an isolated IGBT transistor from a TTL input signal. A unique modulation scheme is used to transmit both power and signal across an isolation boundary with a minimum of external components.
