Part Name(s) : TD300 TD300I TD300ID TD300IN TD300D TD300N ST-Microelectronics
STMicroelectronics
Description : 15V TRIPLE IGBT/MOS DRIVER View

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.
