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
