GR8030 Linear Fan Speed Controller with OTP Function Features Linear fan speed controller Wide fan speed control range Programmable anti-lock start up timer Programmable minimum fan speed Adjustable fan speed curve slope Programmable knee point and OTP point OTP protection with fault output NTC thermistor open full speed operation SOT-26 package Description The GR8030 is designed for programming the curve of DC fan speed versus temperature via a NTC thermistor and few counts of passive components. The speed curve includes anti-lock with full speed operation time, minimum fan speed when at idle state, a knee point where fan speed starts to accelerate when temperature over the set point, a programmable slope of fan speed versus temperature, and OTP (over-temperature protection) trig point.
