10 BIASING OF THE MR ELEMENT
This preamplifier has been designed for SAL and GMR elements. Programming bit GMR in Reg. 01 select either a SAL
range (LOW) or a GMR range (HIGH).
By programming bit PORI in Reg. 01, the user can program either a constant current bias (LOW) or a constant power
bias (HIGH) for the MR element. The value of the current/power is programmed on 5 bits via Reg. 02.
If bit PORI in Reg. 01 is HIGH, a constant power bias is maintained accross the MR element.
The power is defined as :
Pw = RMR * IMR
In power bias mode, two power ranges are possible :
2
, where Pw is constant over temperature and process.
For SAL heads
1.5mW to 9.25 mW
in steps of 0.25mW
For GMR heads
375uW to 2.3 mW
in steps of 0.0625mW
Note :
whatever Power programmation is used, the I
MR
current flowing into the MR element will be within the min-
max range given below.
If bit PORI in Reg.01 is LOW, then the biasing scheme shall revert to constant current instead of constant power.
IMR is then constant over temperature and process.
In current bias mode, two current ranges are possible :
For SAL heads :
4 to 10.2 mA in steps of 0.2 mA
For GMR heads :
3 to 6.1 mA in steps of 0.1 mA
Note :
In GMR mode, I
MR
current is guaranted up to 5.1mA
6.1mA can be reached under certain supplies/Rmr conditions.
10.1
MR Head Resistance and Temperature Measurement
By programming RANGE0,RANGE1 bits in Reg. 08, the user can select either a Rmr measurement or a Temperature
measurement (junction temperature).
Setting DIGON bit HIGH launch a digitazation
The settling time of the digitization operation is less than
TBD
μ
s.
A 5 bit code is then available in Reg. 08, as long as DIGON stays HIGH,
Setting DIGON bit LOW, reset the 5 bit code.
In case of Rmr measurement, the user have access to two Rmr range by programming RANGE0 and RANGE1 bits.
In case of Temperature too high condition (T > 140
o
C), during a Temperature measurement, a Fault is triggered on FLT
line and a error code is available in Reg. 07.
