Design Notes
If large current flows on the power supply (VS) line and the GND line, then in some applications and layouts, misoperation due to
line oscillation may result.
The modes during which large current flows are as follows:
. 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.
The following points should be kept in mind regarding the pattern layout:
. Keep the wiring lines thick and short in order to reduce wiring inductance between the power supply (VS) and GND.
. Insert a passthrough capacitor near the IC. (Maximum effect is obtained by inserting the passthrough capacitor between VS and
. 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 kin series between the CPU and the LB1836M inputs.
