Help nmn po, xe problem q po kung, pano q po mpagsasama in 1 ckt, ang USB charger at 9V(rechargeable) operated RJ45 tester. meron po kc aqng Ni-MH n 9v. nakita q po ung ckt d2 ng charger wid indicator, pde po b un lgyan ng LOAD & CAPACITOR parallel sa BATT? e2 po ung ckt.

Help naman po, kasi problem ko po kung, pano ko po mapagsasama in 1 ckt, ang USB charger at 9V(rechargeable) operated RJ45 tester. meron po kasi akong Ni-MH n 9v. nakita ko po yung ckt dito ng charger with indicator, pede po ba un lagyan ng LOAD & CAPACITOR parallel sa BATT? e2 po ung ckt.

kung gagamitin mo ang charger that you posted, 12-15V ang required input voltage niyan.
medyo malabo yata pagkaintindi ko sa question mo...hehehe
what do you mean "USB charger"? 9V NiMh charger from a 5V(USB port) source? kung ganyan ang setup, you need the MC34063 as boost converter, i-step-up mo yung 5V into a required charging voltage ng 9V mo....
if ibang scenario ang nasa isip mo:na mag-iinput ka ng 12-15V then may output na 5V para maka-charge ng usb-charging capability devices, pwede nga yang nasa itaas.

pa sensya na po sa tanong ko, bale po tama yung isa,
"if ibang scenario ang nasa isip mo:na mag-iinput ka ng 12-15V then may output na 5V para maka-charge ng usb-charging capability devices, pwede nga yang nasa itaas."
yan po bale yung naisip po naming project proposal, gagawa po muna aq ng ckt, then hopefully po matapos ko, para po mapakita ko po sa inyo agad,
ano po b ang value ng capacitor na pede ko pong ilagay parallel sa BATT?
at tanong po ulit, hindi po b makakaapekto ang LOAD ko, hindi "ko po lam term dun",doon po sa Indicator ng BATT(if full or hindi)?
maraming salamat po sir macky.

maybe 100nF will do, di naman masyadong complicated ang requirement.
affected ng LOAD ang battery indicator mo kung if it is a "current" hungry circuit,siguro lagyan mo na lang ng switch(cut-off) sa LOAD when charging...

depende kung mataas ang mAh ng 9V rechargeable battery mo, at depende rin kung ano yung icha-charge mo... |
