Why L6498D Driver, Not Work in High-Side?

Hello, I have a problem with the L6498D driver, the high- side doesn’t work designed a driver for a full h- bridge using two L6498D when I activate the LIN input the LVG output is activated and manages to turn on the low side MOSFET, but when I activate the HIN input I get a strange output of9.6 v on HVG and I’m using 12v at VCC of the L6498D. This strange voltage position always appears, when I always keep the HIN input high or when there’s a PWM in HIN, in both situations the HVG output is always the same,9.6 v.

What could be happening?
