Description
- The bq24721 is a high efficiency synchronous battery pack charger with high level of integration for portable applications. This device implements a high performance analog front-end that interfaces to the system power management micro-controller through a simplified SBS-like SMBus interface.
- The dynamic power management (DPM) function modifies the charge current depending on system load conditions, avoiding ac adapter overload.
- High accuracy current sense amplifiers enable accurate measurement of either the charge current or the ac adapter current, allowing termination of nonsmart packs and monitoring of overall system power.
- The adapter isolation diode can be bypassed or entirely replaced with an external MOSFET using a control signal provided by the bq24721, thus reducing overall power dissipation.
- Integrated features such as charger soft start, charge overcurrent protection, and IC temperature monitoring provide a second level of protection, in addition to pack and system protection functions.
- High Efficiency NMOS-NMOS Synchronous Buck Converter With User-Selectable 300 kHz or 500 kHz frequency
- bq24721C Offers Softer Turn-On, Stronger Turn-Off
- SBS-Like(1) SMBus Interface for Control and Status Communications With Host
- Programmable Battery Voltage, Charge Current, and AC Adapter Current via SBS-Like SMBus Interface
- 0.4% Charge Voltage Regulation Accuracy
