.Sh NAME
.Nm adm1026hm
.Nd Analog Devices ADM1026 complete thermal system management controller
.Sh SYNOPSIS
.Cd "adm1026hm* at iic0 addr 0x2e: ADM1026 hardware monitor: rev. 0x4, step. 0x5"
.Cd "adm1026hm*: 8 fans, 3 temperatures, 15 voltages"
.Sh DESCRIPTION
The
.Nm
driver provides support for the Analog Devices ADM1026 hardware monitor.
The chip possesses 8 fan speed sensors, 3 temperature sensors,
and 17 voltage sensors.
The number of each sensor type configured by the driver depends on the
chip configuration.
.Pp
The values of the sensors are made available through the
.Xr envstat 8
interface.

The
.Nm
driver was written by
.An Julian Coleman Aq Mt jcoleman@NetBSD.org .
.Sh BUGS
It's not possible to determine if either a sensor is not connected,
or the monitored device is producing no output.
Therefore, unconnected sensors will show outputs of 0.
.Pp
The
.Nm
driver does not support checking or altering limit values, interrupt output,
nor the built-in EEPROM.
