Byte

offset

Meaning

4 Lower high byte of maximum voltage.

5 Upper low byte of maximum voltage.

6 Upper high byte of maximum voltage.

7-24 Reserved

Example: Suppose you want to set the maximum voltage to 16.000V. Since 1 represents 1mV,

16.000V translates to 16,000 in decimal. With 4 bytes in Hex, that would be 0x00003E80. Since the

bytes are ordered in little-endian format, 0x80 would be the 3

byte, 0x3E the 4

byte, 0x00 as 5

byte, and 0x00 as the 6

byte.

0x23 Read the maximum voltage allowed

Byte

offset

Meaning

3 Lower low byte of maximum voltage. 1 represents 1 mV.

4 Lower high byte of maximum voltage.

5 Upper low byte of maximum voltage.

6 Upper high byte of maximum voltage.

7-24 Reserved

0x24 Set the maximum current allowed

Byte

offset

Meaning

3 Lower low byte of maximum current. 1 represents 0.1 mA.

4 Lower high byte of maximum current.

5 Upper low byte of maximum current.

6 Upper high byte of maximum current.

7-24 Reserved

Example: Suppose you want to set the maximum current to 3.0000A. Since 1 represents 0.1mA,

3.0000A translates to 30,000 in decimal. With 4 bytes in Hex, that would be 0x00007530. Since the

bytes are ordered in little-endian format, 0x30 would be the 3

byte, 0x75 the 4

byte, 0x00 as 5

byte, and 0x00 as the 6

byte.

0x25 Read the maximum current allowed

Byte

offset

Meaning

3 Lower low byte of maximum current. 1 represents 0.1 mA.

4 Lower high byte of maximum current.
