Design Notes
If large current flows on the power supply (V
line oscillation may result.
The modes during which large current flows are as follows:
.
.
The following points should be kept in mind regarding the pattern layout:

voltage
Motor surge current when the DC motor starts up or when it shifts rotation directions (forward O reverse).
Passthrough current generated within the IC when shifting rotation directions (forward O reverse) or when shifting from
forward/reverse rotation to braking, or vice versa.
Keep the wiring lines thick and short in order to reduce wiring inductance between the power supply (V
Insert a passthrough capacitor near the IC. (Maximum effect is obtained by inserting the passthrough capacitor between V
the pin 7 GND at the closest distance possible.
If the CPU and the LB1836M are mounted on separate boards and the difference between the ground potential of each board is
large, install resistors of about 10 k

Note) Both GNDs must be connected. P-GND of OUT2 and OUT4 and S-GND of the
IN 2, 4
control section are connected to the pin 7 GND within the IC, and P-GND of OUT1
and OUT3 is connected to the pin 14 GND.
