BQ24770: ACFET, RBFET, BATFET and RAC are not in use

Sam Ting

Part Number: BQ24770

Hi Team,

We have a battery docking design with five bq24770. The ACFET, RBFET, BATFET and input sense resistor (RAC) are not in use.

Can these pins be floating? Thanks!

CMSRC
ACDRV
CMPIN
CMPOUT
# BATPRES
# BATDRV

Best regards,

Hi Sam,

If not used, I recommend:
1. CMSRC be connected to ACP
2. ACDRV leave floating
3. CMPIN should be connected to GND per datasheet
4. CMPOUT leave floating
5. /BATPRES connected to GND
6. /BATDRV leave floating
