BQ24450: BQ24450 BATTERY DETECTION

Regarding 1, the bq24450 does not have integrated battery detection. User should initiate charging by controlling CE pin. 

Regarding 2, if CE pin is frequently on-off, then battery charging will correspondingly frequently on and off. 

Hi Jing ,
1. Is there any other way or any circuitry with that i can detect the battery is connected with this controller?
2. you can suggest any other controller similar to BQ24450. i have to recharge 12V -7 Ah battery with 0.5 amp current.

You can also have a look at bq24650 for lead acid battery charging. Below is an application note for bq24650 charging lead acid battery.

Hi Jing,

how BQ24450 can be safe from battery reverse polarity connection ?
i.e what will happen if i will connect the battery in reverse polarity ?

Please clarify the doubts.
