The warning is detected with the A/D converter resulting in latency up to 90ms, typical. This command has two data bytes and is formatted in Linear_5s_11s format. VIN_ON The VIN_ON command sets the SVIN input voltage, in volts, at which the unit should start power conversion. This command has two data bytes and is formatted in Linear_5s_11s format. VIN_OFF The VIN_OFF command sets the SVIN input voltage, in volts, at which the unit should stop power conversion. This command has two data bytes and is formatted in Linear_5s_11s format. Output Voltage and Limits COMMAND NAME CMD CODE DESCRIPTION TYPE PAGED DATA FORMAT UNITS NVM DEFAULT VALUE VOUT_MODE 0x20 Output voltage format and exponent (2–12).

Must be greater than VOUT_COMMAND. R/W Word Y L16 V Y 1.05 0x10CD VOUT_COMMAND 0x21 Nominal output voltage set point. R/W Word Y L16 V Y 1.0 0x1000 VOUT_MARGIN_LOW 0x26 Margin low output voltage set point. Must be less than VOUT_COMMAND. R/W Word Y L16 V Y 0.95 0x0F33 VOUT_UV_WARN_ LIMIT 0x43 Output undervoltage warning limit. R/W Word Y L16 V Y 0.925 0x0ECD VOUT_UV_FAULT_ LIMIT 0x44 Output undervoltage fault limit. R/W Word Y L16 V Y 0.9 0x0E66 MFR_VOUT_MAX 0xA5 Maximum allowed output voltage including VOUT_OV_FAULT_LIMIT. R Word Y L16 V 5.7 0x5B34 VOUT_MODE The data byte for VOUT_MODE command, used for commanding and reading output voltage, consists of a 3-bit mode (only linear format is supported) and a 5-bit parameter representing the exponent used in output voltage Read/Write commands. This read-only command has one data byte. |
