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.
