Isolated Drive Transmitter

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.

User Programmable Fault Timing

Screens False Fault Signals

Shutdown Mode Disables On Chip

Logic Reference for Low Standby

Power

•

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.
