Features

 Intended for use with the host MCU, this IC chip

converts signals (electrical angle information)

detected by the resolver sensor (angle sensor) to

digital signals.

 Connectable to a transformer-type or currentdetection

type resolver sensor of single-phase

excitation input and two-phase output structure

 Integrated exciter amplifier (excitation frequency:

5 kHz, 10 kHz, or 20 kHz)

 Resolution of the angle signal (electrical

angle):16,000 pulses/rotation

(excitation frequency: 5 kHz; operating frequency

of the host MCU timer: 80 MHz)

 Correction of errors in the detected signals from the resolver

 Correction of the residual carrier in the signals

detected by the resolver sensor

 Analog filters to eliminate the resolver’s magnetic

noise and PWM noise from motor control

 Error detection

 Detection of disconnection from the resolver sensor

 Detection of an excessive temperature within the IC chip
