No.A1515-7/8
The standard data transfer to this device consists of three bytes : the slave address of the first byte and the data of the
second and third bytes.
Slave address : 0110011(0)
PD : Power-down
D1-D7 : 8-bit data used to set output constant current ; MIN = 00000000, MAX = 11111111

Relationship between the ENA pin input, I
2C input data PD, and current setting 0 (code 0)
This IC supports the following three modes of setting up the standby mode :
1) Setting the ENA pin low.
2) Setting the PD bit to 1 (high) with I
2C input data.
3) Setting the output current to 0 with I
2C input data.
Execution of one of the steps 1) to 3) causes the output current to 0 and stops operation of the circuit.
When the ENA pin is set low, the I
2C data register is reset and the IC is reset to its default state (PD bit set to 0 and output
current setting to code 0).
Since the IC starts operation in the data reset state at power-on time, it is necessary to start using the IC in the default state
by setting the ENA pin low before turning on VCC and then high after VCC is established.
