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

spike cannot prematurely retrigger the monostable.
