DESCRIPTION

The TD310 is designedto driveone, two or three Power IGBT/MOS and has driving capability for pulse transformer.So itis perfectlysuited to interface control IC with Power Switchesin low side or half-bridgeconfiguration.

The typicalapplication shown figure 1 implements the TD310 in a pulse controlled half-bridgedrive. 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 andshort-circuit protectionas shownin application note n°AN461.

On Figure2, TD310is implementedas a low side driverin a typical 3 phase motor drive.

Figure 3 presentsa generalpurposelow side gate drive.

In both case, the current amplifier provides interfacing between a senseresistor and anA/D converter.

INSTRUCTIONS FORUSE

1 - The TD310 supply voltage must be decoupledwith a 1µF min.capacitor. 2 - If theapplicationinvolving TD310 requires maximum output current capability,

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