12description: |
13  The RT9756/RT9757 is a high efficiency and high charge current charger.
14
15  The efficiency is up to 98.2% when VBAT = 4V, IBAT = 2A in DIV2 mode and 99.1%
16  when VBAT=4V, IBAT=1A in bypass mode. The maximum charger current is up to 8A
17  in DIV2 mode and 5A in bypass mode. The device integrates smart cap divider
18  topology, direct charging mode, external over-voltage protection control, an
19  input reverse blocking NFET and 2-way regulation, a dual phase charge pump
20  core, 8-Channel high speed ADCs and USB BC 1.2 detection.
21
22  RT9770 is almost the same with RT9756/57, only BC 1.2 detection function is
23  removed to shrink the die size.
