OUTSLOPE, in the analog mode case, defines the power limit above which the output driver turns off to
prevent damages to the IC.
The power dissipated in the IC output driver is measured by the IC itself. The power is obtained by multiplying
continuously the voltage across the conducting MOS driver by the output current I
reaches the power limit, the output driver is switched off and on such that, on average, the measured power
is maintained equal to the power limit. For OUTSLOPE = 3, the output driver is always enabled independently
of the measured power.
Table 18: Output power limitation in analog mode
(1) Factory settings: OUTSLOPE = 3.
OUTSLOPE, in the PWM mode case, defines the rise and fall times of the PWM transients.
Table 19: PWM rise and fall time, Cout = 10nF, Rpullup = 4.7kOhms
The PWM duty cycle definition is as follows.
Table 20: PWM duty cycle definition
RATIODIS allows enabling and disabling the ratiometry of the output in reference to the supply voltage by
setting a 1 as value. By default the MLX91207 is programmed in ratiometric mode
