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. The GR8030 sends a low level on FSC pin
when the OTP pin is lower than the set point of
temperature protection level. It is also built-in the
NTC thermister open with full speed operation
function.
