9 / 17 page TD350 Functional description Doc ID 9525 Rev 6 9/17 5.6 Minimum ON time In order to ensure the proper operation of the 2-level turn-off function, the input ON time (Twin) must be greater than the Twinmin value: Twinmin=Ta+2*Rdel*Coff Rdel is the internal discharge resistor and Coff is the external timing capacitor. Input signals smaller than Ta are ignored. Input signals larger than Twinmin are transmitted to the output stage after the Ta delay with minimum width distortion (ΔTw=Twout-Twin). For an input signal width Twin between Ta and Twinmin, the output width Twout is reduced below Twin (pulse distortion) and the IGBT could be partially turned on. These input signals should be avoided during normal operation. 5.7 Output The output stage is able to sink 2.3 A and source 1.5 A typical at 25 °C (1.2 A/0.75 A minimum over the full temperature range). Separated sink and source outputs allow independent gate charge and discharge control without an extra external diode. 5.8 Fault status output Fault output is used to signal a fault event (desaturation, UVLO) to a controller. The fault pin is designed to drive an optocoupler. 5.9 Undervoltage protection Undervoltage detection protects the application in the event of a low VH supply voltage (during start-up or a fault situation). During undervoltage, the OUTH pin is open and the OUTL pin is driven low (active pull-down for VH>2 V, passive pull-down for VH<2 V). Fault output signals the undervoltage state and is reset only when undervoltage state disappears. Figure 3. Undervoltage protection VH OUT 2V UVH UVL Vccmin FAULT |
