- E nānā i ka ʻikepili huahana no ka hana kikoʻī pin.
- Nīnau: Pehea wau e mana ai i ka papa loiloi?
- A: E hoʻoikaika i ka papa ma ka hoʻopili ʻana i kahi vol bias DVtage ma waena o nā pine VCC a me GND.
- Nīnau: He aha kaʻu e hoʻopili ai e nānā i ka hopena?
- A: Hoʻohui i ka pine OUT i kahi voltmeter kikohoʻe a i ʻole oscilloscope no ka nānā ʻana i nā huahana.
- Nīnau: Ma hea e loaʻa ai iaʻu ka ʻike kikoʻī pin?
- A: E nānā i ka ʻikepili huahana no nā kikoʻī kikoʻī o ka hana pin.
HOIKE
Hoʻolālā ʻia ka papa loiloi CTD221-BB-1.5 e hōʻike i nā mana ʻike o kēia manawa o ka CT220 linear magnetic sensor mai Allegro MicroSystems. ʻO ka CT220 kahi mea ʻike maka ʻole i kēia manawa e pili ana i ka ʻenehana XtremeSense™ tunnel magnetoresistance (TMR). Hōʻike ia i kahi hoʻonohonoho alahaka piha e loaʻa ana i ʻehā mau mea TMR monolithically i hoʻohui pū ʻia me ka circuitry CMOS ikaika, e ʻae iā ia e loaʻa i ka hoʻonā kiʻekiʻe a me ka leo haʻahaʻa i kahi wāwae wāwae liʻiliʻi. Hōʻike kēia alakaʻi mea hoʻohana pehea e hoʻopili ai a hoʻohana i ka papa loiloi CTD221-BB-1.5.

Hoʻoikaika ʻia ka papa loiloi ma ka hoʻopili ʻana i kahi vol bias DVtage ma waena o nā pine VCC a me GND ma ka PCB. Pono e hoʻopili ʻia ka pine OUT o ka PCB i kahi voltmeter kikohoʻe (DVM) a i ʻole kahi oscilloscope e nānā i ka hoʻopuka ʻana o ka mea ʻike i kēia manawa CT220. ʻO ka ʻikepili i loaʻa ma kēia ʻāpana no kahi vol bias 5 Vtage.
ʻAno Haʻahaʻa-I kēia manawa
Ma ke ʻano haʻahaʻa haʻahaʻa, hele ka mea i kēia manawa ma kahi ʻāpana ākea 0.9 mm ma ka papa luna o ka PCB. Hiki ke hoʻohana ʻia kēia ʻano no ke ana ʻana i nā au i ka laulā o ± 3.85 A. ʻO ka hoʻomaʻemaʻe ʻana ma waena o ka trace a me nā pads IC he 0.35 mm, e hāʻawi ana i kahi kaʻawale o 1 kV ma waena o ka trace o kēia manawa a me nā pine SOT23. Ma waho aʻe o ka linearity maikaʻi loa ma waena o ka mahana, ʻo ke kiʻekiʻe signal-to-noise ratio (SNR) o ka CT220 hiki iā ia ke ana i nā au haʻahaʻa loa. Hiki i ka CTD221 ke ʻike i nā au i lalo o 5 mA.
ʻAno Kūwaena-I kēia manawa
Ma ke ʻano waena-i kēia manawa, hele ka mea i kēia manawa ma kahi ʻāpana ākea 2 mm ma ka papa lalo o ka PCB. ʻO kēia ʻākea ākea (hoʻohālikelike ʻia me ke ʻano haʻahaʻa haʻahaʻa) hiki ke ʻike ʻia kahi au nui. Hiki ke hoʻohana ʻia kēia ʻano no ke ana ʻana i nā au o ± 10 A, me ka hiki ke hoʻoholo i nā ʻanuʻu 10 mA. ʻO ka hoʻokaʻawale ʻana o ka CT220 no kēia hoʻonohonoho he 5.1 kVrms no ka mea ʻo 23 mm ka mamao ma waena o ka ʻaoʻao lalo a me nā pine SOT1.6.
ʻAno Kiʻekiʻe-I kēia manawa
Hoʻohana ʻia ke ʻano kiʻekiʻe o kēia manawa no nā noi e pili ana i nā au i ʻoi aku ka nui o ka hele ʻana ma nā ʻāpana PCB. Ma kēia ʻano, hele ʻia ke ʻano i loko o kahi busbar keleawe.
