Xtar MC1 has 2-TP4057 they are marked with 57b6 or 57bM

XTAR MP1 modd

Being curios creature I "googled" some IC markings from MP1 PCB and found out that "heart" of this charger is SE9017 chip (http://www.alldatasheet.com/datasheet-pdf/pdf/292099/SEAWARD/SE9017.html) with really nice features. XTAR was very considerate when designing this charger as they used two of these IC in parallel conne…
