DESCRIPTION

· The RT9515 is a low-cost, fully integrated single-cell Li-Ion battery charger IC designed for portable applications.
· It supports power from an AC adapter and enters sleep mode when the adapter is removed.
· Features a control algorithm with preconditioning, fast charge, and constant voltage modes.
· Charging terminates when the current drops below a preset threshold.
· AC adapter charge current is programmable up to 1A with an external resistor.
· Includes thermal feedback to optimize charge rate across all ambient temperatures.

FEATURES

· Maximum 18V rating for AC adapter.
· Integrated P-MOSFETs.
· Indicators for AC adapter power good status and charge status.
· Protections include under voltage and over voltage.
· Automatic recharge feature.
· Battery temperature monitoring.
· Compact 10-Lead WDFN package.
· RoHS compliant and halogen-free.

APPLICATIONS

· Digital cameras.
· Cellular phones.
· Personal Data Assistants (PDAs).
· MP3 players.
· Handheld PCs.
