Figure 8. Output Current Regulation Waveforms
Figure 9 shows the magnitude of the Off Time tOFF versus COFF and ROFF values. It can be approximately cal-
culated from the equations:
tRCFALL = 0.6 ROFF COFF
tOFF = tRCFALL + tDT = 0.6 ROFF COFF + tDT
where ROFF and COFF are the external component values and tDT is the internally generated Dead Time with:
20K
≤ ROFF ≤ 100K
0.47nF
≤ COFF ≤ 100nF
tDT = 1s (typical value)
Therefore:
tOFF(MIN) = 6.6s
tOFF(MAX) = 6ms
These values allow a sufficient range of tOFF to implement the drive circuit for most motors.
The capacitor value chosen for COFF also affects the Rise Time tRCRISE of the voltage at the pin RCOFF. The
Rise Time tRCRISE will only be an issue if the capacitor is not completely charged before the next time the
monostable is triggered. Therefore, the on time tON, which depends by motors and supply parameters, has to
