35 / 151 page  Note: since current limitation makes use of shunt sensing, the blanking time programmed for CH3/CH7 has no effect in detection timings. The blanking time has only effect on FETs using DSM. Figure 18.

This latch is cleared on SPI readout. The OFF time interval for current limitation (tOFF) is selectable via SPI according to HBx_toff bit: L9945 H-Bridge DS12275 - Rev 8 page 35/151 |
