IP5389-4.0

Please read the following text instructions and chip manual carefully before asking any questions! ! !
 
Modification based on the V2.0 version "IP5389+BM3451 two-way 100-watt fast charging mobile power supply solution" (click on the text to jump)
 
Updated features:
more reasonable layout,
higher original component density,
perfectly adapted aluminum alloy shell
, smaller PCB size ( Size only 80*25mm)
Better heat dissipation design (all heating devices are on the back and can be dissipated through thermal pads and casing)
 
Integrated 4 string protection board
The maximum input and output power is 100W
Only supports 4 strings of ternary lithium batteries (TYP 3.7V)
Some chips of the mobile power supply are IP5389_BZ
protection board and some chips are BM3451TNDC_T28A

Aluminum alloy shell purchase link (click the text to jump) If you need to customize 132-135mm length,
you only need one, you can send me a private message (PS: Someone made too many orders to meet the minimum order quantity, I won’t tell who it is)
 
Attention! ! ! The battery terminal current is relatively large when the input and output are high. Pay attention to the battery selection (LG M50T 21700 OR Samsung 50S is recommended). I will not go into the introduction of the chip. If you need it, you can look at the previous project. The 5-string version is completed
 
directly as shown in the picture above .
