PS21997-4A

The trademark registered by MITSUBISHI ELECTRIC CORPORATION in Japan is "PS21997-4/-4A/-4C/-4W."

The application of the PS21997-4 Integrated Power Functions module is for control supply voltage, input voltage, fault output supply voltage, fault output current, and current sensing input voltage. It is also used for sink current at the FO terminal and control supply variation. Additionally, it is applied for arm shoot-through blocking time and PWM input frequency.

The functions integrated into the PS21997-4 module include supply voltage, control supply voltage, collector-emitter voltage, each IGBT collector current, collector dissipation, junction temperature, arm shoot-through blocking time, PWM input frequency, and current sensing input voltage.
