RT9471D Datasheet | Richtek

Description The RT9471/D is a highly-integrated 3A switch mode battery charge management, and system power path management device for single cell Li-Ion and Li Polymer batteries. The low impedance power path optimizes switch-mode operation efficiency, reduces battery charging time, and extends battery life during the discharging phase. The I2C serial interface with charging and system settings makes the device a truly flexible solution. The remended junction temperature range is - 40C to 125C, and the ambient temperature range is - 40C to 85C. 2 Ordering Information RT9471/D Pin 1 Orientation(1) (2): Quadrant 2, Follow EIA-481 Package Type(2) QW: WQFN-24L 4x4 (W-Type) (Exposed Pad-Option 2) Lead Plating System(3) G: Richtek Green Policy pliant Function Support Default: Pin2 : PSEL, Pin3: PG D: Pin2 : D+, Pin3: D- Note 1. - Marked with (1) indicated: Empty means Pin 1 orientation is Quadrant 1. - Marked with (2) indicated: patible with the current requirements of IPC/JEDEC...
