Hello,
Please reference page 22 of BQ24250/1/3 datasheet. The first paragraph of page 22 has the following statement about BQ24251:
"The /PG pin will remain high impedance state until the detection is completed."
Does this statement equally apply to BQ24253?
Details:
I have no need for D+/D- pins (floating), and want to use an external resistor to set max charging current. Furthermore, I prefer to use Stand Alone mode. However, based on 1 or 2 other forum posts here, there needs to be about a 700ms - 1s delay before changing EN1 state. /PG appears to do this automatically, page 22 of the datasheet.
My goal: to use BQ24253 /PG pin as indirect trigger for EN1 pin, to set "Externally programmed by ILIM" of Table 1, page 22. Therefore, I need to know if the datasheet statement above applies equally to BQ24253.
Can I use BQ24253 /PG pin to appropriately trigger EN1? (EN2 will be permanently connected to GND.)
Best Regards,
David McRell
