hi there,
i would like to do burn-in test for fan-driver-chip, because of the high temp and space in oven, so i must replace the fan with a load.
output current is 500mA, voltage output is 12V, and fan-driver is a single-coil driver with 2 output drive pin.
1) what load should i use to replace the fan? resistor or coil?
load power-dissipate is P=500mA*12V=6Watt, if use resistor, then R=P/I² which is 24 ohm. is this correct ??
2) how do i imitate the hall input to fan-driver (which come from hall-sensor when the fan rotate) ??
thanks in advance.
rgds,
