Notes 1.

Source clock of the free-running counter.

tR, tF is not tested in production, specified by design.

The slew rate control generates a cross current in the output stage to control the energy of the external

inductive load. The cross current flows only during the output transition time tR, tF. It flows in addtion to the

output current. The cross current is not tested, but derived from simulation.

The output buffer can not generate high or low pulses shorter than this time, because of its slew rate

control system. This value is not tested, but derived from simulation.

The slew rate control function causes a deviation of output pulse time compared to the ideal selected

output pulse setting. This value is not tested, but derived from simulation.

Indicates the dispersion of 16 PWM output voltages. (4 buffers’ output voltage differences in the state of IOH

(IOL) at the same time.) Not tested in production, specified by design.
