1 Introduction

The TD351 is an advanced IGBT driver with integrated control and protection functions. It is a simplified

version of the TD350, available in an SO8 or DIP8 package. The TD35x family (including the TD350,

TD351 and TD352) provides a wide range of drivers specially adapted to drive 1200 V IGBTs with current

ratings of 15 to 75 A in Econopak-like modules (see

The main features of the TD351 are:

Applications include three-phase full-bridge inverters such as in motor speed control and UPS systems

1 A sink/0.75 A source peak output current minimum over the full temperature range (-20°C to

125°C),

active Miller clamp function to reduce the risk of induced turn-on in high dV/dt conditions, and in

most cases, without requiring a negative gate drive,

optional 2-step turn-off sequence to reduce over-voltage in case of an over-current or a short-

circuit situation; a feature that protects the IGBT and avoids RBSOA problems,

input stage compatible with both an optocoupler and a pulse transformer.
