Cautions 1. The undervoltage lockout detection circuit (UVLO) operates at 1.7 V TYP. whereupon the
output goes into a Hi-Z state. Internal data such as the excitation position information is
reset. The UVLO circuit does not operate after reset.
2. A shutdown circuit that prevents a current from flowing into the V
M
pin when V
DD
= 0 V is
provided.
