2 / 8 page Specifications Absolute Maximum Ratings at Ta = 25°C Allowable Operating Ranges at Ta = 25°C Electrical Characteristics at Ta = 25°C, VCC = 5 V, VS = 15 V Notes : 1. The torque ripple correction ratio is determined as follows from the Rf voltage waveform. Continued on next page. 2. Parameters that are indicated as design target values in the conditions column are not tested.
