Design Notes

The L9698-TR can dissipate up to 2.5W during ignition pulses. Ensure adequate PCB copper area and thermal vias to the exposed pad to keep the junction temperature within limits. A minimum of 1 square inch of copper is recommended for continuous operation at high duty cycles.

Place the input capacitor (0.1uF) close to the IN pin and the current sense resistor close to the SENSE pin to minimize noise. The high-current collector and emitter traces should be short and wide to reduce parasitic inductance and resistance.

Do not exceed the maximum collector-emitter voltage of 400V. Ensure the input signal is clean and free of glitches to prevent false triggering. The current sense output should be filtered with a small capacitor to avoid noise interference.
