AN1944 APPLICATION NOTE TD350 advanced IGBT driver Principle of operation and applications by Jean-François GARNIER & Anthony BOIMOND 1 INTRODUCTION The TD350 is an advanced IGBT driver with integrated control and protection functions. The TD350 is especially adapted to drive 1200V IGBT with current ratings from 15 to 75A in Econopak-like modules (see Figure2). Main features are:
1.2A sink / 0.75A source peak output current minimum over full temperature range (-20°C to 125°C).
Desaturation protection with adjustable blanking time and fault status signal.
Active Miller clamp function to reduce the risk of induced turn-on in high dV/dt conditions, without the need of negative gate drive in most cases.
Optional 2-step turn-off sequence to reduce over voltage in case of over current or short-circuit event, to protect IGBT and avoid RBSOA problems.
Input stage compatible with both optocoupler and pulse transformer. Applications include three-phase full-bridge inverter like motor speed control and UPS systems (see Figure1).
