US79 Series
CMOS Power Hall IC
7. Unique Features
Reverse voltage protection eliminates the need for a diode. Reverse current flows through the coils and
the chip. Power dissipation is (2 * Istall/Istart * 0.7V).
Table 1 presents max temperature for each current.
Reverse Voltage protection is provided by the motor windings.
The 35V Zener diodes clamp the output drivers for overstress protection.
