Note:

•

In case of VFQFPN32 package, CFG_0.DIS_EN and bit CFG_0.NRES_N need to be set through SPI.

•

In case of HTSSOP24 package, NRES and DIS pins are not available; CFG_0.DIS_EN and bit

CFG_0.NRES_N must be considered as reserved, kept at ‘0’.

•

For both package options the exposed pad must be left floating to guarantee the reverse battery

protection feature.
