BQ24640 EVM Evaluation

Other Parts Discussed in Thread: BQ24640

Hi,

I'm currently evaluating EVM for BQ24640

 VBAT measured voltage is 0.8423V with open load (no load)

The R14 = 0.8436MΩ(measured by multimeter) & R15 = 100kΩ 

If based on formula below, the VBAT should 19.8156V

Formula Vout = 2.1V x [1+R14/R15]

 Remark other condition:

a)JP1 = short by jumper BATDRV with BATDRV_IN

b)JP2 = short by jumper ACDRV with ACDRV_IN

c)JP3 = short by jumper VREF with VPULLUP

d)JP4 = short by jumper VPULLUP with CHGEN

e)JP5 = short by jumper VPULLUP with LEDPWR

Kindly advise.
