Overview
The R2A30406SP is a semiconductor integrated circuit that incorporates
driver circuits suitable for the motors of digital cameras.
By adopting an ultra-fine CMOS process, H bridge 4-ch of a full-swing
drive was built in one chip.
It is considering as the high composition flexibility to realize low power
consumption and miniaturization.
Features
 All bridges can be controlled independently.
An ultra-fine CMOS process has been adopted for low power
consumption in a design with no charge-pump.
 Built-in H bridge of a full-swing drive 4 circuit
 Built-in low-voltage malfunction prevention circuit
 Power supply systems are all internally isolated and include
a function to prevent reverse current between power supplies.
 It is housed in a small package (24SSOP 6.5x6.4 mm t=1.0mm)
Applications
Motor driver for digital cameras, digital video camera, etc.
Recommended operating conditions
Power-supply voltage range — VCC:2.5~5.5V VM :2.5~5.5V
Rated power-supply voltage — VCC:3.0V
VM :5.0V

Since loads such as motors and coils are inductive, overshoots may occur on the power-
supply voltage pin. Therefore, we recommend the connection of a roughly 10-µF capacitor
between the VM pin and GND.

As for the control input pins, the 100Kohm inverter is built in pull down resistance .
It will operate, if the terminal is set as H-Active.
When the control input pins use is not carried out, ensure that the control input pins are either grounded or
open-circuit (disconnected) while power is being supplied.
