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
