M50224FP
1.5 Channel Motor Driver·with DC/DC Control
REJ03F0070-0100Z
Rev.1.0
Sep.19.2003
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.
Features
Minute CMOS process acceptance.Low consumption
1.5 full swing voltage drive H Bridge circuit built-in (PWM drive correspondence)
DC/DC circuit built-in of 5V
One AE operation circuit built-in AE (A sensor corresponds to amorphous and SPD)
Low voltage incorrect operation prevention circuit thermole shutdown circuit built-in
A thermometer, with a power save function
Application
motor driver for cameras etc
Recommend Operating Condition
Supply voltage range........ VB:1.6V to 3.5V
Rated supply voltage VB:3.0V

*: Please pass through the Brake or Stand-by mode by all means in case of moving from forward rotation to
Reverse rotation or from
Reverse rotation to forward rotation by the motor control.
(ex.) Forward rotation -> Brake -> Reverse rotation,Reverse rotation -> Stand-by -> Forward rotation
