Brief Description
The ZSSC5101 is a CMOS integrated circuit for con-
verting sine and cosine signals obtained from
magnetoresistive bridge sensors into a ratiometric
analog voltage with a user-programmable range of
travel and clamping levels.
The ZSSC5101 accepts sensor bridge arrangements
for both rotational as well as linear movement.
Depending on the type of sensor bridge, a full-scale
travel range of up to 360 mechanical degrees can be
obtained.
Programming of the device is performed through the
output pin, allowing in-line programming of fully
assembled 3-wire sensors. Programming param-
eters are stored in an EEPROM and can be re-pro-
grammed multiple times.
The ZSSC5101 is fully automotive-qualified with an
ambient temperature range up to 160°C.
Features
Ratiometric analog output
Up to 4608 analog steps
Step size as small as 0.022°
Programming through output pin via
one-wire interface
Offset calibration of the bridge input signals
Programmable linear transfer characteristic:
Zero position
Angular range
Upper and lower clamping levels
Rising or falling slope
Loss of magnet indication with programmable
threshold level
Accepts anisotropic, giant, and tunnel magneto-
resistive bridge sensors (AMR, GMR and TMR)
Programmable 32-bit user ID
CRC, error detection, and error correction
on EEPROM data
Diagnostics: broken-wire detection
Automotive-qualified to AEC-Q100, grade 0
Benefits
No external trimming components required
PC-controlled configuration and single-pass
calibration via one-wire interface allows
programming of fully assembled sensors
Can be used with low-cost ferrite magnets
Allows large air gaps between sensors and
magnets
Optimized for automotive environments with
extended temperature range and special
protection circuitry with excellent electro-
magnetic compatibility
