Question about LTC6813

Hi All,

 

My battery spec is as follows.

- Battery total voltage: 378V, The number of cells: 120,  Voltage per cell: 3.15V (3.15Vx120=378V)

I cosinder to use 8 x LTC6813 to monitor each cell voltage. 8 x LTC6813s are connected in series and one (1) LT6813

monitors 15 cells as attached.

Any problem, especially high voltage is applied to upper LTC6813s, about this connection?

 

Regards,

Kazu
