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. June 1998 V CC + 1 2 3 4 5 6 7 14 13 12 11 10 9 8 N.C.
