Part Number : BQ24630
Function : Stand-Alone Synchronous Switch-Mode Lithium Phosphate Battery Charger With System Power Selector and Low Iq / 300-kHz NMOS-NMOS Synchronous Buck Converter
Manufacturers : Texas Instruments
Pinouts :
Description :
The bq24630 is a highly integrated switch-mode battery charge controller designed specifically for lithium phosphate batteries. It offers a constant-frequency synchronous PWM controller with high-accuracy current and voltage regulation, charge preconditioning, termination, adapter current regulation, and charge status monitoring.
The bq24630 charges the battery in three phases:
preconditioning, constant current, and constant voltage. Charge is terminated when the current reaches a minimum user-selectable level. A programmable charge timer provides a safety backup. The bq24630 automatically restarts the charge cycle if the battery voltage falls below an internal threshold and enters a low-quiescent-current sleep mode when the input voltage falls below the battery voltage.
