nxp75a — NXP LM75A
Digital temperature sensor and thermal watchdog
nxp75a* at iic? addr?
The nxp75a driver provides support for the
NXP LM75A temperature sensor, with a temperature resolution of 0.125 degC
and a single programable high limit. Both the temperature value and the
limit are available through the
envstat(8) interface.
Note, that although this chip is described as a "pin-for-pin replacement for industry standard LM75" it is not software compatible with it. The LM75 and similar chips are supported via the lmtemp(4) driver.
The nxp75a driver first appeared in
NetBSD 11.1.
The nxp75a driver was written by
