The LB1836M dual H-bridge driver and how it applies to toy, or small brush DC motors is shown on this slide. The process technology used in this device enables low saturation, low voltage drive, and low cost at the same time, utilizing a PNP transistor for the high side motor output. By separating the control power supply this device supports a motor power supply of 1.8 V minimum, which allows motor operation with two batteries. As shown in the lower left, Sanyo’s process technology incorporates the protection diode for the high-side PNP transistor while it is necessary for the competition to add an external diode or use die space to do this internally. The figure in the lower right illustrates the low saturation voltage and low voltage drive advantages of this part. In the case of a power supply voltage of 2.4 V, the competition can only deliver about 1.5 V to the motor, while the SANYO part delivers 2.3 V. These technology and design advantages provide the designer with board space reduction as well as longer battery life.
