1.3 Description

The LM93, hardware monitor, has a two wire digital interface compatible with SMBus 2.0. Using an 8-bit

ΣΔ ADC, the LM93 measures the temperature of two remote diode connected transistors as well as its

own die and 16 power supply voltages.

To set fan speed, the LM93 has two PWM outputs that are each controlled by up to four temperature

zones. The fan-control algorithm is lookup table based. The LM93 includes a digital filter that can be

invoked to smooth temperature readings for better control of fan speed. The LM93 has four tachometer

inputs to measure fan speed. Limit and status registers for all measured values are included.

Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of

Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.

PRODUCTION DATA information is current as of publication date. Products conform to

specifications per the terms of the Texas Instruments standard warranty. Production

processing does not necessarily include testing of all parameters.
