SLUSCC7C July 2016 – June 2018 TPS546C23
The TOFF_FALL command sets the time in milliseconds, from the end of the TOFF_DELAY time until the voltage reaches 0 V. The contents of this register can be stored to nonvolatile memory using the STORE_DEFAULT_ALL command.
Programming a value of 0 instructs the unit to bring its output voltage down to 0 as quickly as possible. For the TPS546C23 device, this results in actively ramping down the output voltage in 1 ms (the fastest supported ramp down).
For loop slave device, this command cannot be accessed. Any writes to this command will be ignored. An attempt to read or write this command will result in a NACK’d command, the reporting of an IVC fault, and triggering of SMB_ALERT.
The TOFF_FALL command is formatted as a linear mode two’s complement binary integer.
|Format||Linear, two's complement binary|
