ZL9101M
VOUT_MAX (24h)
Definition: The VOUT_ MAX command sets an upper limit on the output voltage the unit can command regardless of any other
commands or combinations. The intent of this command is to provide a safeguard against a user accidentally setting the output
voltage to a possibly destructive level rather than to be the primary output overprotection.
Data Length in Bytes: 2
Data Format: L16u
Type: R/W Word
Default Value: 1.10 x VOUT_COMMAND pin strap setting
Units: Volts
Range: 0V to 4V
VOUT_MARGIN_HIGH (25h)
Definition: Sets the value of the VOUT during a margin high. This VOUT_MARGIN_HIGH command loads the unit with the voltage to
which the output is to be changed when the OPERATION command is set to “Margin High”.
Data Length in Bytes: 2
Data Format: L16u
Type: R/W Word
Default value: 1.05 x VOUT_COMMAND pin strap setting
Units: Volts
Range: 0V to VOUT_MAX
VOUT_MARGIN_LOW (26h)
Definition: Sets the value of the VOUT during a margin low. This VOUT_MARGIN_LOW command loads the unit with the voltage to which
the output is to be changed when the OPERATION command is set to “Margin Low”.
Data Length in Bytes: 2
Data Format: L16u
Type: R/W Word
Default value: 0.95 x VOUT_COMMAND pin strap setting
Units: Volts
Range: 0V to VOUT_MAX
VOUT_TRANSITION_RATE (27h)
Definition: This command sets the rate at which the output should change voltage when the device receives an OPERATION command
(Margin High, Margin Low) that causes the output voltage to change. The maximum possible positive value of the two data bytes
indicates that the device should make the transition as quickly as possible.
Data Length in Bytes: 2
Data Format: L11
Type: R/W Word
Default value: BA00h (1.0 V/ms)
Units: V/ms
Range: 0.1 to 4V/ms
