I ka honua o nā ʻāpana uila, ʻo ka mea hoʻoponopono voltage kekahi o nā mea i hoʻohana nui ʻia, akā he aha ka hana a kēia IC?Hāʻawi ia i kahi kaapuni me ka mana hiki ke wānana a paʻa i nā manawa a pau, me ka nānā ʻole i ka volta komo.
Pehea e hoʻokō ai ka mea hoʻoponopono voltage i kēia hana, aia i ka mea hoʻolālā.Hiki ke hoʻomalu ʻia kekahi volta e kahi diode Zener maʻalahi, aʻo nā noi ʻē aʻe e koi i kahi topology holomua o nā mea hoʻoponopono laina a hoʻololi paha.I ka hopena o ka lā, ʻo kēlā me kēia mea hoʻoponopono voltage he pahuhopu mua a lua:
Kumumua:No ka hoʻoulu ʻana i ka uila puka paʻa o kahi kaapuni i ka pane ʻana i nā ʻano like ʻole o kahi kūlana uila hoʻokomo.Loaʻa paha iā ʻoe ka 9V i loko, akā inā makemake ʻoe i ka 5V i waho, a laila pono ʻoe e iho i lalo (Buck) me kahi mea hoʻoponopono uila.
lua: Ke hana pū nei nā mea hoʻoponopono uila e pale a pale i kāu kaapuni uila mai nā pōʻino.ʻO ka mea hope āu e makemake ai, ʻo ia ka hoʻomoʻa ʻana i kāu microcontroller no ka mea ʻaʻole hiki iā ia ke hoʻopaʻa i ka spike i ka volta.
I ka hoʻohui ʻana i ka mea hoʻoponopono uila i kāu kaapuni, e hana maʻamau ʻoe me kekahi o nā ʻano ʻelua - Linear Voltage Regulators a i ʻole Switching Voltage Regulators.E ʻike kākou i ka hana ʻana o kēia mau mea ʻelua.
Nā hiʻohiʻona no ka TPS7B69-Q1
- Kūpono no nā noi kaʻa
- ʻO AEC-Q100 kūpono me nā hualoaʻa aʻe: 4 a 40-V Wide VIVoltage Hookomo
- Ka Mahana Meahana Papa 1: –40°C a i 125°C
- Kaulana wela o ka hana ʻana
- Helu 2 ka papa helu HBM ESD
- Papahana CDM ESD Classification Level C4B
- Māhele Me ka 45-V Transient
- Loaʻa i kēia manawa: 150 mA
- ʻO ke au haʻahaʻa haʻahaʻa haʻahaʻa (IQ): 450-mV maʻamau Haʻahaʻa Haʻalele Voltage ma 100 mA Haawe
- 15 µA maʻamau i nā haʻawe māmā
- 25 µA Kiʻekiʻe ma lalo o ka wela piha
- ʻO kēia manawa
- Paʻa me ka ESR Ceramic Output Capacitor
- (2.2 i 100 µF)
- Paʻa 2.5-V, 3.3-V, a me 5-V Nā Koho Voltage
- Hoʻopaʻa hewa i hoʻohui ʻia:
- Paʻa wela
- Palekana Pokole
- Nā pūʻolo:
- 4-Pin SOT-223 Pūʻolo
- 5-Pin SOT-23 Pūʻolo
ʻO ka wehewehe ʻana no ka TPS7B69-Q1
ʻO ka hāmeʻa TPS7B69xx-Q1 kahi mea hoʻoponopono laina haʻahaʻa haʻahaʻa i hoʻolālā ʻia a hiki i 40-VVInā hana.Me ka 15-µA wale nō (maʻamau) i kēia manawa ma ka haʻahaʻa māmā, kūpono ka hāmeʻa no nā ʻōnaehana microcontrol-unit standby ma nā noi kaʻa.
Hōʻike nā mea hana i kahi pale pōkole i hoʻohui ʻia a me ka overcurrent.Hoʻohana ʻia ka polokalamu TPS7B69xx-Q1 ma luna o ka pae wela -40°C a 125°C.Ma muli o kēia mau hiʻohiʻona, ua kūpono nā mea TPS7B6925-Q1, TPS7B6933-Q1, a me TPS7B6950-Q1 i nā lako mana no nā noi kaʻa like ʻole.
