TPS1H100-Q1: Driving inductive load

Part Number: TPS1H100-Q1

Hello,

Can you please let me know how internal clamp diode connected to drain to gate is helping to clamp negative OUT pin voltage during inductive load turn off? I am not able to figure out complete path for inductive energy dissipation

 .

  • Hello,
    The internal clamp does not conduct the demagnetizing current. The clamp circuit provides a voltage on the gate and turn on the FET once drain to source voltage (Vs - VOUT = Vclamp). The FET conducts the current while the voltage across drain to source is around 55V typical.
