AN2511

14/43

Doc ID 13286 Rev 2

Description

The VOUT_OV_WARN_LIMIT command sets the

value of the output voltage at the sense or output

pins that causes an output voltage high warning.

This value is typically less than the output

overvoltage threshold.

SMBus transaction type

VOUT_UV_WARN_LIMIT

Command name

VOUT_UV_WARN_LIMIT

Command code

43h

Description

The VOUT_UV_WARN_LIMIT command sets the

value of the output voltage at the sense or output

pins that causes an output voltage low warning.

This value is typically greater than the output

undervoltage fault threshold

SMBus transaction type

Read/ Write word

Number of data bytes

Table 13.

IOUT_OC_FAULT_LIMIT

Command name

IOUT_OC_FAULT_LIMIT

Command code

46h

Description

The IOUT_OC_FAULT_LIMIT command sets the

value of the sense output current, in amps (literal

format), that causes an overcurrent fault.

SMBus transaction type

Read/ Write word

Number of data bytes

Table 14.

IOUT_OC_WARN_LIMIT

Command name

IOUT_OC_WARN_LIMIT

Command code

4Ah

Description

The IOUT_OV_WARN_LIMIT command sets the

value of the output current that causes an output

overcurrent warning.

SMBus transaction type

Read/ Write word

Number of data bytes

Table 15.

OT_FAULT_LIMIT

Command name

OT_FAULT_LIMIT

Command code

4Fh

Description

The OT_FAULT_LIMIT command sets the value

of the sense temperature, in °C (literal format),

that causes an overtemperature fault
