... LB11824M Function Description 1. Output drive circuit This IC employs a direct PWM drive method to minimize the power loss at output. The output TR is normally saturated in the ON condition, adjusting the motor drive power by changing the output on-duty. Output PWM switching is made on UH, VH, and WH output sides. Since and UH- WH outputs are of the same output form, either lower PWM or upper PWM can be selected by changing the external output Tr connection method ...

... Instead, use an electrolytic capacitor to suppress the inrush current and to prevent voltage rise. 13. VREG stabilization To stabilize the V voltage that is the power supply for the control circuit, connect a 0.1µF or more capacitor REG between V and GND. The capacitor GND must be wired near the GND pin much as possible. REG LB11824M 1 pin and GND No. 7107-16/17 ...
