Part Number:BQ24616
Hello Everyone,
In order to disable the Fast charge timer , we have connected the TTC pin of charger IC to Vref using a Zero Ohms resistor( 3.3 Regulator Output from Charger IC). While it is being tested , we have faced that the Reference Voltage from charger IC is 2.8 Volts Instead of 3.3 Volts.
After debugging we have found that TTC pin is causing the Reference of the charger IC to be lower than 3.3 volts i.e 2.8 Volts.
Since Vref is changed our Voltage and current setting to charger IC have varied.
Could you tell us what is the potential root cause for the TTC pin failure ?? Does it require any Pull Up resistor between TTC and VREF to rectify the failure??
Appreciate Your reply at the earliest.
