Puna: Toshiba TB62209FG rārangi raraunga

Ko te tauira tono a Toshiba e whakamahi ana i ngā uara tohu e whai ake nei:

Komihana	Hononga, uara
Hiko pūnaha, VM	24 V
Hiko rorohiko, VDD	5 V
Pāmahana tohu, Vref	3.0 V
He rēhi whakarara hiko	0.66 Ω mo ia waahanga
Kapasita hiko rorohiko	10 µF

Kāpata tohu	1 µF
Kāpata pākākano	0.22 µF me 0.022 µF
He rēhi oscillator	3.6 kΩ
He kapasita oscillator	560 pF

Pārai te 0.66 Ω he rēhi whakarara hiko i honoa i waenganui i te VM me te RS A/RS B e ai ki te whakaahua tauira a Toshiba. Ko ngā uara kāpata pākākano 0.22 µF me 0.022 µF e pā ana hoki ki te tauira tono a Toshiba.

Tirohanga Te Whakarite Hiko

Ki te Vref = 3.0 V, he 0.66 Ω rēhi whakauru mo ia waahanga, me te TORQUE kua whakaritea ki te 100%, ko te paerewa a te hiko he tawhiti teitei:

(3.0 V ÷ 5) ÷ 0.66 Ω = 0.91 A ia waahanga

He tūtohi tēnei e pā ana ki te paerewa hiko e whakawhirinaki ana ki te whakatipu tohu i te wātea i te wā. E whakatauhia ana e Toshiba te tino pā maunga Vref hei 1/5.0, me te āta ka riro atu te ōna, nō reira ko te hiko me te pikinga pāmahana e whakawhirinaki ana ki ngā tatauranga wāhanga me ngā tikanga whakahaere.

Ngā Kōwhiringa Tiaki

Kei roto i te TB62209FG ngā aho tiaki e pā ana ki ngā tikanga hapa kua whakatau, engari kāore e whakarite te tiaki i ngā hapa katoa.

Rūkai Hiko Tahu, ISD: Ka huri ngā putanga ki waho i te wā e kitea ana te tikanga rūkai hiko kua whakatuwherahia. Ka tuku pū e Toshiba te hiko ISD e kitea ana hei 3.0 A. I te wa e aktivetia ana, kei te haere tonu te taimaha rūkai kia ngaro i te STANDBY e kawea ki te Low, ā, hei konei ki te High.

Rūkai Pāmahana, TSD: Ka huri ngā putanga hiko e rua ki waho i te wā e pā ki te pāmahana huinga ki te rōpū rūkai pāmahana. E whakatau ana a Toshiba i te rōpū mahi TSD hei 130°C ki 170°C. Ko te whakahohe e hiahia ana hei ki atu te taputapu ki te pāmahana iti tāpu ki te rongoā. Ka noho pāmamao te STANDBY kāore e whakahoki i te TSD i te wā kei te wera rawa te huinga.

Tirotiro Hiko: Ka whakahou te tirotiro i roto i te wā ka huri te pāmahana hiko ki raro i tōna taumahatanga.

PROTECT: Ko tēnei putanga he tohu anake mō te rūkai pāmahana. E kī ana a Toshiba ka piki te PROTECT ki VDD i te wā e pahi ana te TSD. Me kāore e kīhia hei putanga hapa noa.

Ko ēnei kōwhiringa tiaki hei whakautu kupu e pā ana ki ngā tikanga kua whakaritea. Me whai taputapu maia te rautaki mamau hiko, ngā hoahoa pāmahana, te taiao tīwae, te whirihora, me te tātaritanga hapa.
