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 (forwardOreverse). .Passthrough current generated within the IC when shifting rotation directions (forwardOreverse) 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 kΩ in series between the CPU and the LB1836M inputs. Note) Both GNDs must be connected. P-GND of OUT2 and OUT4 and S-GND of the 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.

As shown in the above diagram, the Vcont pin outputs the voltage of the band gap Zener VZ+V F (= 1.93 V). In normal use, this pin is left open. The drive current I D is varied by the Vcont voltage. However, because the band gap Zener is shared, it functions as a bridge. Control Thermal shutdown Control Note: As long as the voltages applied to VCC ,V S1, VS2, and IN1 through IN4 are within the limits set by the absolute maximum ratings, there are no restrictions on the relationship of each voltage level in comparison with the others (regarding which is higher or lower).
