Description
M50224FP is the semiconductor integrated circuit which builds in the Motor drive circuit and DC/DC circuit suitable
for the camera etc.
1.5 H bridges, the DC/DC circuit of 5VDC/DC, and AE operation circuit were built in one tip by adoption of a detailed
CMOS process.
The reduction in power consumption and the miniaturization are considered as the high composition of the flexibility
realized with one chip.
