The VOUT_MIN command sets the minimum output voltage. The purpose is to protect the devices on the output rail supplied by this device from a lower than acceptable output voltage. VOUT_MIN imposes a lower bound to any attempt to program the output voltage to a VOUT_EQUIV setting by changing any of the following registers:
The exponent is set be VOUT_MODE at –9 (equivalent of 1.953 mV/count). Use Equation 8 to calculate the programmed output voltage.
The range of valid VOUT_MIN values is dependent upon the configured (29h) VOUT_SCALE_LOOP as shown in Equation 9.
If, while the output voltage is turned on, any attempt is made to program: (1) VOUT_EQUIV to be less than VOUT_MIN, the device will:
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.
