In datasheet, CHRG status pin will change once the c/10 pass below its threshold regardless ctimer. However, we find our CHRG pin is abnormal in practical and simulation.
According to datasheet and flowchard, CHRG status pin will DEASSERT once the c/10 pass below its threshold. However, after ctimer is set, CHRG pin remain assert after c/10 below threshold. CHRG status pin will only DEASSERT after the ctimer termination.
The issue is observed in my simulation too. When the timer is set, the CHRG pin is not working even c/10 below threshold. It only happened when I remove ctimer feature.
In datasheet, CHRG status pin pulls low during a charging cycle until the charger output current falls below the C/10 threshold, regardless which termination scheme is
Appreciate if you can advise how CHRG pin status behave with c/10 and ctimer.
