+.Sh NAME
+.Nm tda
+.Nd Tadpole PMU 
+.Sh SYNOPSIS
+.Cd "Tadpole PMU Version 1.33"
+.Sh DESCRIPTION
+The
+.Nm
+driver provides basic support for the Tadpole PMU found in Tadpole SPARCle
+and Viper systems.
+The status of the AC adapter, battery and fan are reported via the
+.Xr envstat 8
+interface, and AC adapter and lid switch events are reported via the
+.Xr sysmon_pswitch 9 interface.
+.Sh SEE ALSO
+.Xr envstat 8
+.Sh BUGS
+The battery status is reported by reading the battery voltage.
+Pp.
+The points at which the battery level becomes warning and critical are
+reported by the PMU, but are not directly correlated with battery voltage,
+so might be misreported by the driver.
