Hardware Monitor with Integrated Fan Control for Server Management

LM93 Features

* (i.e. smart tachometer mode). It also adds measurement and control support for dynamic Vccp monitoring and PROCHOT. It is designed to monitor a dual processor Xeon class motherboard with a minimum of external components. n Dual dynamic VID monitoring (6 VIDs per processor) n 8 general purpose I/Os:

LM93 General Description

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