ZSSC5101

Datasheet

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.

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

Power supply monitoring

Sensor monitoring

Detection of EEPROM memory failure

Connection failure management

High accuracy: ± 0.15° integral nonlinearity (INL)

after calibration

Features

•

Ratiometric analog output

Up to 4608 analog steps

Step size as small as 0.022°

Programming through output pin via

one-wire interface

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
