INPUT STEP CIRCUIT DIAGRAM

VREG OUTPUT CIRCUIT DIAGRAM

VREG output voltage can be selected with RREG exterior

resistance.

If VREG is not used (as in the case of double−phase

magnetization), use pin (7) in the open position.

(Do not connect to VCC or GND pins.)

Use the following formula to obtain the output voltage.

VOUT ≈ VREG ≈ RREG × 56 × 10−6
