BQ24095-based charger does not work

Other Parts Discussed in Thread: BQ24095

I designed a simple battery charger based on BQ24095.

Despite the fact that I sticked to the  schematics found in the datasheet, the charger does not work.

Please see the schematic here below:

RIset is 1K and this should give a current of circa 0.5A

TS not needed, so a fixed resistor is used

PRETERM is disconnected, because the default currents are OK. Anyway, the batteries that I tested were well above the Vlowv

Of course there is the correct voltage on pin 1 (measured).

I really can't see the error, could someone give me a hint?

Thanks
