DESCRIPTIO N

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 prot ection 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 purpos e low side gate drive.

In both case, the current amplifier provides interfacing between a sense resistor and an A/D converter .

INSTRUCTIONS FOR USE

1 - The TD300 supply voltage must be decoupled with a 1µF min. capacitor. 2 - If the application involving TD300 requires maximum output current capability,

this current must be pulsed : pulse width 1µsec, duty cycle 1% at T
