LM93 Overview

The LM93, hardware monitor, has a two wire digital interface patible 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 controlled by up to four temperature zones.

LM93 Key Features

  • 4 can be configured as fan tachometer inputs
  • 2 can be configured to connect to THERMTRIP from a processor
  • 2 are standard GPIOs that could be used to monitor IERR signal n 2 general purpose inputs that can be used to monitor SC
  • Supports byte/block read and write
  • Configurable slave address (tri-level pin selects 1 of 3 possible addresses) n 2.5V reference voltage output n 56-pin TS
  • LM93 Operational
  • Remote Temp Accuracy n Power Supply Voltage n Power Supply Current n n n n
