2 : RFG
Current detection resistor connection pin
The current detection resistor (1Ω) is connected between
this pin and GND to detect the output current and perform
constant current control.
3 : OUT
Output pin
This is an NMOS open drain output, and the voice coil
motor is connected between this pin and the V CC pin for
use.
4 : V CC
Power supply input pin
5 : V DD
This is separate from the V CC power supply pin for the
SDA, SCL and PD logic input, and it is used while the
same voltage as that for the high level of these logic input
is applied to it.

Input high level : 0.8 × V DD or higher
Input low level : 0.2 × V DD or lower

Power down and reset
When low, power-down and reset is performed at the
same time.
This pin is held high for normal use.
In normal operation, however, this pin must be set low
temporarily and an initial reset must be applied after V CC
starts up.
Input high level : 0.8 × V DD or higher
Input low level : 0.2 × V DD or lower
