iC-MH16
12-BIT ANGULAR HALL ENCODER
preliminary
Rev A1, Page 2/25
DESCRIPTION
The iC-MH16 12-bit angular encoder is a position
sensor with integrated Hall sensors for scanning a
permanent magnet. The signal conditioning unit gen-
erates constant-amplitude sine and cosine voltages
that can be used for angle calculation. The resolu-
tion can be programmed up to a maximum of 4 096
angular increments per rotation; the zero position is
adjustable.
The commutation interface with the signals U, V and
W provides 120 ° phase-shifted signals for block com-
mutation of EC motors with up to 16 pole pairs.
The integrated serial interface also enables the posi-
tion data to be read out to several networked sensors.
The integrated memory can be written embedded in
the data protocol.
The incremental interface with the pins A, B and Z
supplies quadrature signals with an edge rate of up
to 16 MHz. Interpolation is performed with maximum
resolution at a speed of 200 000 rpm.
The RS422-compatible outputs of the incremental in-
terface are programmable in the output current and
the slew rate.
In conjunction with a rotating permanent magnet, the
iC-MH16 module forms an one-chip encoder including
protection against a reversed power supply voltage.
The entire configuration can be stored in the internal
parameter ROM with zapping diodes. The integrated
programming algorithm assumes writing of the ROM
structure.
