L297/1 Frequently Asked Questions (FAQs)

  • The maximum voltage that can be applied to the VCC pin is 20V, but it's recommended to keep it between 8V and 15V for optimal performance.
  • The value of Rs and Ct depends on the maximum current and the desired current sensing accuracy. A good starting point is to use Rs = 0.1 ohm and Ct = 2.2nF, and then adjust based on the specific application requirements.
  • The bootstrap capacitor (Cb) is used to generate the high-side gate drive voltage. A good value for Cb is between 10nF and 100nF, depending on the switching frequency and the gate drive current requirements.
  • To ensure proper synchronization, the external oscillator or clock signal should be connected to the CLKIN pin, and the SYNC pin should be tied to VCC. The L297/1 will then synchronize its internal clock with the external clock signal.
  • The L297/1 can operate up to 100 kHz, but the maximum frequency depends on the specific application and the external components used.
