Part Number: BQ76200
Hello,
I' m usind following schematics for my circuit:
For Charging part:
with RCHG = 470ohm, Rb=100ohm, Cb=10nF, Rgs_chg2=4.7Mohm, Rgs_chg1=10Mohm
For discharging part:
with: Rdsg=470ohm, Rgs=10Mohm, Rp=56ohm and capacitor beetwen VPack and rp=10nF.
The capacitor beetwen VDCCP and Vbat is 1uF.
The VBat is 12.4V.
CP_EN is alway ON,
PMON_EN and PCHG_EN are Always OFF.
The mosfet Q1, and Q2 are STL120N8F7 (but I tried also BSC010N04LSI). I don' t have PCHG mosfet.
Whit CHG_EN and DSH_EN i have this:
Yellow=VDDCP
heavenly=VBAT
but when I switch ON CHG_EN and DSG_EN I get these on DSG:
Yellow=VDDCP
heavenly=PACK pin
pink=DSG pin
and this on CHG:
Yellow=VDDCP
heavenly=BAT pin
pink=CHG pin
I tried to change the Vddcp capactor from 10nF to 22uF, but never changed except the start time.
I tried to change the Rchg and Rdsg from 0ohm to 33kohm but never changed.
I don' t understand why it doesn't work!!!
