13 / 27 page ![]() DocID018993 Rev 3 13/27 L6207Q Circuit description 27 Figure 10 shows the typical operating waveforms of the output current, the voltage drop across the sensing resistor, the RC pin voltage and the status of the bridge. Immediately after the low-side Power MOSFET turns on, a high peak current flows through the sensing resistor due to the reverse recovery of the freewheeling diodes. The L6207Q device provides a 1 s blanking time tBLANK that inhibits the comparator output so that this current spike cannot prematurely retrigger the monostable. Figure 10.
