Toshiba Electronics Europe TLP5231 IGBT/MOSFET

The TLP5231 is a pre-drive photocoupler for medium to high current IGBT and MOSFET

The TLP5231 is a pre-drive photocoupler for medium to high current IGBT and MOSFET, for industrial inverters and photovoltaic (PV) power conditioning systems. The new pre-drive photocoupler delivers various built-in functions*, including an overcurrent detection by monitoring collector voltage. Toshiba's TLP5231 controls the gates of medium to high current IGBT and MOSFET by using external p-channel and n-channel complementary MOSFET as buffers. It is housed in a tiny SO-16L surface mount package.

[*] Gate signal soft turn off, fault feedback function

 

Key features

• Smart Gate Driver with built-in protection circuit
• Dual output driver
• Peak output current ±2.5 A
• Gate signal soft turn off, fault feedback function

 

Additional features

• Dual outputs with built-in active timing control, suitable for driving p-channel and n-channel complementary-MOSFET buffers
• Configurable gate soft turn-off time using another external n-channel MOSFET when overcurrent is detected.
• Fault signals are output on the primary side when overcurrent is detected by monitoring collector voltage, or when a UVLO is detected.

Other Advantages

• Can drive p-channel and n-channel MOSFET
• No external protection circuit needed

Benefits

• Simplifies design tasks
• SO16L package with high isolation performance for safety-critical applications

 

Applications

• IGBT and power MOSFET gate drivers (pre-drivers)
• AC and brushless DC motor control
• Industrial inverters
• Photovoltaic (PV) power conditioning systems
• Uninterruptible power supplies (UPS)
