DESCRIPTION
The TD300 is designed to drive one, two or three
Power IGBT/MOS and has driving capability for
pulse transformer. So it is perfectly suited to interface control IC with Power Switches in low side or
half-bridge configuration.
The typical application shown figure 1 implements
the TD300 in a pulse controlled half-bridge drive.
Positive and negative pulses are applied to the
pulse transformer to charge and discharge the
IGBT/MOS gate capacitance. More sophisticated
secondary circuits provide low impedance gate
drive and short-circuit protection as shown in application note AN461.
On Figure 2, TD300 is implemented as a low side
driver in a typical 3 phase motor drive.
Figure 3 presents a general purpose low side gate
drive.
In both case, the current amplifier provides interfacing between a sense resistor and an A/D
converter.

INSTRUCTIONS FOR USE

2/8
The TD300 supply voltage must be decoupled with a 1µF min. capacitor.
If the application involving TD300 requires maximum output current capability,
this current must be pulsed : pulse width 1µsec, duty cycle 1% at Tamb.
