+.Sh DESCRIPTION
+The
+.Nm
+driver provides support for the Microchip Technology
+MCP9805/98242 and other chips that conform to JEDEC Standard 21-C section
+4.7.
+Memory module temperature sensors are optional on DDR2 and newer DIMMs.
+Sensors provided by this driver, including the on-chip thresholds for the
+Alarm Window and Critical level, are accessed through the
+.Xr envsys 4
+API.
+.Pp
+The
+.Nm
+supports temperature ranges from -256 to +255 degrees C.
+.Pp
+Chips supported by the
+.Nm
+driver include TSE2004av compliant devices and:
