The bq2425x is a highly integrated single-cell Li-Ion battery charger with integrated current sense resistor targeted for space-limited, portable applications with high capacity batteries. The single cell charger has a single input that operates from either a USB port or AC wall adapter for a versatile solution. BC1.2 compatible D+, D- detection allows for recognition of CDP, DCP, SDP, and non-standard USB adapters. The use of an accessory dead battery provision (DBP) pin allows for the system to sync a dead battery state in order to enable or disable the BC1.2 detection in the event of an external USB-PHI.

The bq24257 has two modes of operation: 1) I2C mode, and 2) Standalone mode. In I2C mode, the host can adjust the charge parameters and monitor the status of the charger operation. In Standalone mode, the external resistor sets the input current limit, charge current limit, and the input DPM level. This mode also serves as the default settings when a DCP adapter is present. The bq24257 enters host mode while the I2C registers are accessed and the watchdog timer has not expired (if enabled).

For all available packages, see the orderable addendum at the end of the datasheet.

All trademarks are the property of their respective owners.

The bq24258 has only one mode of operation which is the Standalone. In this mode, the external resistor sets the input current limit, charge current limit, and the input DPM level. This mode also serves as the default settings when a DCP adapter is present. The EN1, EN2, and EN3 pin are available in the bq24258 spin to support USB 3.0 compliance.

The battery is charged in four phases: trickle charge, pre-charge, constant current and constant voltage. In all charge phases, an internal control loop monitors the device junction temperature and reduces the charge current if the internal temperature threshold is exceeded. Additionally, a voltage-based, JEITA compatible battery pack thermistor monitoring input (TS) is included that monitors battery temperature for safe charging.
