LMTEMP(4)		 BSD Kernel Interfaces Manual		     LMTEMP(4)

NAME
     lmtemp — National Semiconductor LM75, LM77 and compatible hardware moni‐
     tors

SYNOPSIS
     lmtemp0 at iic? addr 0x48 flags 0x0000

DESCRIPTION
     The lmtemp driver provides support for the National Semiconductor LM on
     iicbus series temperatures and register compatible chips to be used with
     the envsys(4) API.	 The lmtemp supports ranges of the temperature between
     +125 from -55.

     Each device is specified by the value of the address and flags.

	   Temperature	  addr		   flags
	   LM75		  0x48 - 0x4f	   0x0000
	   DS75		  0x48 - 0x4f	   0x0001
	   LM77		  0x48 - 0x4b	   0x0002

HARDWARE
     Chips supported by the lmtemp driver include:

	   National Semiconductor LM75

	   National Semiconductor LM77

	   Dallas Semiconductor DS75

SEE ALSO
     envsys(4), envstat(8)

HISTORY
     The lmtemp device appeared in NetBSD 4.0.

BUGS
     Interrupt support is unimplemented.
