2N5551HR LCC-3 Package Pin Orientation

Looking at the 2N5551HR datasheet pages 7 - 9, it is misleading where pin 1 is located. If you look at the UB package on page 7, pin 1 seems to be on the opposite side to the ident and dot. Does this also mean the LCC-3 package is also wrong. Can ...

I'm using the STC4054 Li-ion single cell charger in a design, the CHRG pin is supposed to have a weak pull-down when not charging but the current drawn is higher than specs

In the STC4054 datasheet, it says the CHRG pin is supposed to have a weak pull-down of max 35uA when no battery is connected yet. However, with a 4.7Kohm pullup from that pin to 3.3v, I measure a 1.2v drop, which indicates about 250uA of current. Wit...
