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.
