LM93CIMT/NOPB Datasheet

Motor / Motion / Ignition Controllers & Drivers


The LM93CIMT/NOPB 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. LM93CIMT/NOPB Features • 8-bit ΣΔ ADC• Monitors 16 power supplies• Monitors 2 remote thermal diodes• Internal ambient temperature sensing• Fan control based on 13-step lookup table• Temperature reading digital filter• 1.0°C digital temperature sensor resolution• 0.5°C temperature resolution for fan control• 2 PWM fan speed control outputs• 4 fan tachometer inputs
