3 – 14.4Vdc input; 0.45Vdc to 5.5Vdc output; 20A output current
20A Digital Micro DLynx
Turn Module on or off. Also used to margin the output voltage
Configures the ON/OFF functionality as a combination of analog ON/OFF
pin and PMBus commands
Clear any fault bits that may have been set, also releases the SMBALERT#
signal if the device has been asserting it.
Used to control writing to the module via PMBus. Copies the current register
setting in the module whose command code matches the value in the data
byte into non-volatile memory (EEPROM) on the module
Bit5: 0 – Enables all writes as permitted in bit6 or bit7
Bit 6: 0 – Enables all writes as permitted in bit5 or bit7
Bit7: 0 – Enables all writes as permitted in bit5 or bit6
Copies all current register settings in the module into non-volatile memory
(EEPROM) on the module
Restores all current register settings in the module from values in the
module non-volatile memory (EEPROM)
Copies the current register setting in the module whose command code
matches the value in the data byte into non-volatile memory (EEPROM) on
the module
Restores the current register setting in the module whose command code
matches the value in the data byte from the value in the module non-volatile
memory (EEPROM)
The module has MODE set to Linear and Exponent set to -10. These values
cannot be changed
