7. The formula shown below roughly determines the time, Tprot (s), until the stuck rotor protection
circuit operates. Figure 2 shows the operating waveforms. The latched state can be cleared by
either
CE
or V
. Note that a capacitor with a leakage current sufficiently smaller than the
charging current Ict+ must be used.
