7.5 TSD (Thermal Shut-Down) Protection
IGBT junction temperature). Purpose of this protection is to detect abnormal increase of case temperature.
Cooling fan stop or loose fixing of heat sink will cause it. So this TSD function will not work effectively in the
case of rapid temperature rise like motor lock condition or over current. (This protection measures LVIC
temperature, so it cannot respond to rapid temperature rise of IGBT & FRD)

to the HVICs within the Mini DIP SPM. This supply must be in the range of 13.0~18.5V to ensure that the
HVIC can fully drive the high-side IGBT. The Mini DIP SPM includes an under-voltage detection function for
the V
voltage (refer to the datasheet). This function prevents the IGBT from operating in a high dissipation mode.
bootstrap method described here. This method has the advantage of being simple and inexpensive. However,
the duty cycle and on-time are limited by the requirement to refresh the charge in the bootstrap capacitor.
The bootstrap supply is formed by a combination of an bootstrap diode, resistor and capacitor as shown in
Figure 8.1. The current flow path of the bootstrap circuit is shown in Fig. 8.1. When V
