Description¶

E50SN12051 is a 600W non-isolated 1/8th brick DC-DC power module.

This driver supports the E50SN12051 PMBus compliant monitor device.

The device provides measurements for:

The driver is based on the PMBus core and exposes standard hwmon sysfs attributes.

curr1_label	“iout1”
curr1_crit	Critical maximum current. From IOUT_OC_FAULT_LIMIT register.
curr1_crit_alarm	Current critical high alarm. From IOUT_OC_FAULT status.
curr1_input	Measured current. From READ_IOUT register.
curr1_max	Maximum current. From IOUT_OC_WARN_LIMIT register.
curr1_max_alarm	Current high alarm. From IOUT_OC_WARN_LIMIT status.
in1_label	“vin”
in1_alarm	Input voltage alarm.
in1_input	Measured voltage. From READ_VIN register.
in2_label	“vout1”
in2_crit	Critical maximum voltage. From VOUT_OV_FAULT_LIMIT register.
in2_crit_alarm	Voltage critical high alarm. From VOLTAGE_OV_FAULT status.
in2_input	Measured voltage. From READ_VOUT register.
in2_max	Maximum voltage. From VOUT_OV_WARN_LIMIT register.
in2_max_alarm	Voltage high alarm. From VOLTAGE_OV_WARNING status.
temp1_crit	Critical high temperature. From OT_FAULT_LIMIT register.
temp1_crit_alarm	Module temperature critical high alarm. Set by comparing READ_TEMPERATURE_1 with OT_FAULT_LIMIT if TEMP_OT_FAULT status is set.
temp1_input	Measured module’s hot spot temperature. From READ_TEMPERATURE_1 register.
temp1_max	Maximum temperature. From OT_WARN_LIMIT register.
temp1_max_alarm	Module temperature high alarm. Set by comparing READ_TEMPERATURE_1 with OT_WARN_LIMIT if TEMP_OT_WARNING status is set.
