DC Motor Driver
1.Standby function
2.DCM output control logic
3.Current limit control timing chart
4. Setting the time of current limit brake value
This is can switch the standby – operation mode by setting the ST pin.
On standby-mode, all logic circuit is reset, internal regurator is off, internal charge-pump is off.
This IC can set the time of the current limit break by connecting the capacitor with CHOP-GND.
The value of the capacitor is decided according to the following expression.
brake time: T CHOP ≈ C CHOP × Vt CHOP ÷ I CHOP [sec]
ex. Cchop=50[pF]
Tchop[sec] = 50[pF] × 1.0[V] ÷ 5[μA] = 10[μs]
