Register = 0x0A Product ID (Product_ID)
Used to identify the module ID information, read fixed 0x36, take the mantissa 36 of the
ISM6636.
Table 9 Register = 0x0A
Register = 0x0B Module version (IC_Version)
Used to identify the module version information, and upgrade according to the module
version.
Table 10 Register = 0x0B
Register = 0x0C PVIN voltage report (PVIN_Report)
When the VIN pin of the module is working normally, the PVIN voltage can be read through
the I2C protocol, the reading range is 0~16V, LSB=0.0625V.
Example 1: When the read I2C value is 0x00, it means that the current PVIN voltage is 0V.
Example 2: When the read I2C value is 0xC0, it means that the current PVIN voltage is 12V.
The PVIN voltage reporting function supports up to 16V input voltage, when the voltage
exceeds 16V, the register will display the maximum value 0xFF.

Register = 0x0D Output Voltage Report (Vout_Report)
When the VIN pin is working normally, the output voltage information can be read through
the I2C protocol. The output voltage of this register is related to the mantissa X of the read
range of ISM6636X.
When the part number is ISM6636A or ISM6636B, the output voltage reading range is
0.8~5.7V, LSB=20mV. The formula is as follows:
Vout =
V
Example (ISM6636B): When the read I2C value is 0x8C.
Vout =

Table 12 Register = 0x0D
Register = 0x0E Output current report (Iout_Report)
When the VIN pin is working normally, the output current information can be read through
the I2C protocol. The current can be read in the range of 0A~8.2A, LSB=40mA. There is a
constant offset in reading current information, and the calculation formula can be referred to
as follows:
.
Example: When the read I2C value is 0x72, 0x72=Dec(114)=114*0.04-2.5=2.06A. It means
the current output current is 2.06A.
When the read current exceeds 8.2A, the data fed back by the I2C is either the maximum
value. The output current information is for reference only. It is recommended that the user
read the current range as 0~6A. For accurate current information, also measure with an
external measuring instrument.

Register = 0x0F Module temperature report (Temp_Report)
When the VIN pin is working normally, the temperature information of the module can be
read through the I2C protocol. Temperature readable range is: -40°C~180°C.
LSB=1°C. There is a constant offset in reading temperature information. The calculation
formula can be referred to as follows:
5
Example 1:When the read I2C value is 0x65, 0x65=Dec(101)=101*1-75=26°C. Indicates the
module temperature 26°C.
The reading of temperature information will have a certain offset according to different
usage scenarios, but the maximum deviation will not exceed
±
10°C.

Table 14 Register = 0x0F
Register = 0x11 Ramp compensation amplitude setting (Ramp_Amplitude)
The ISM6636X provides an adjustable ramp compensation (Ramp) setting function. 0x00
indicates the minimum ramp compensation amplitude, 0xFF indicates the maximum ramp
compensation amplitude, and the amplitude increases as the bit increases. The ramp
compensation amplitude will affect the output load transient response (Load transient) and
frequency jitter (Jitter) of the module. When the ramp compensation amplitude increases,
the load transient response may become worse, but the jitter will become better. When the
ramp compensation amplitude is reduced, the load transient response (Load transient) will
be better, but the jitter (Jitter) will be worse. If the factory default settings can meet the
application requirements of the user's load transient response, it is recommended that the
default value is to be used.
