PRELIMINARY INFORMATION - AUG 01, 2011
5.15
The calibration of the IC is performed with the ELMOS standard FUSE-Array cell by the ELMOS ATE
(Automatically Test Equipment) during Final part production test.
5.15.1
The calibrated parameters and the default values are listed in Table 46 below.
1.) Defaults values are valid during a global power on reset phase (see chapter 5.3), during the read out
2.) If the Fuse Array read out fails, the spec parameters of the High side and Low side driver currents in

process of the FUSE Array or if the read out has finished with an error. The default value of the parity
bit (bit[23]) is set to low level to obtain a FUSE_FAIL status (see chapter 5.4.5), if the read out has
finished with an error.
HCM, LCM and Test mode, the oscillator frequency and the 40mA reference current source can be
violated in both directions.
