ʻO ka wehewehe pōkole:

• Hoʻokomo ʻia ka mana o ka uila uila (VIN):
– TPS22992: 0.1 V a 5.5 V
– TPS22992S: 1 V a 5.5 V
• Hāʻawi kaila uila (VBIAS): 1.5 V a i 5.5 V
• ʻO kēia manawa mau loa: 6 A
• Ke kū'ē (RON): 8.7 mΩ (ʻano.)

1.E hoʻokomo i ka pae uila hana (VIN):
– TPS22992: 0.1 V a 5.5 V
– TPS22992S: 1 V a 5.5 V
2.Bias lako uila (VBIAS): 1.5 V a 5.5 V
3.Maximum mau loa: 6 A
4. On-kū'ē (RON): 8.7 mΩ (type.)
5. Hiki ke hoʻoponopono i ka mana pepehi
6. Hoʻokuʻu wikiwiki wikiwiki (QOD)
7.Open drain Power Good (PG) hōʻailona
8.Low mana hoʻohana:
– ON state (IQ): 10 µA (typ.) no TPS22992
– ON state (IQ): 30 µA (type.) no TPS22992S

ʻO ka ʻohana huahana TPS22992x he ʻelua mau mea hana: TPS22992 a me TPS22992S.ʻO kēlā me kēia hāmeʻa he hoʻololi hoʻoili hoʻokahi-kanela me kahi 8.7-mΩ powerMOSFET i hoʻolālā ʻia e hoʻonui i nā noi haʻahaʻa mana a hiki i 5.5 V a me 6 A. ʻO ka manawa hiki ke hoʻonohonoho ʻia e hāʻawi i ka maʻalahi no ka hoʻopili ʻana i ka mana a me ka hōʻemi ʻana i ka manawa inrush no nā ukana capacitance kiʻekiʻe. hiki i ka pin (ON), hiki ke hoʻopili pololei me nā hōʻailona voltageGPIO haʻahaʻa (VIH = 0.8 V).Loaʻa i ka mea hana TPS22992x kahi pine QOD koho no ka hoʻokuʻu wikiwiki ʻana i ka wā e pio ai ka hoʻololi, a hiki ke hoʻoponopono ʻia ka manawa hāʻule (tFALL) o ka hopena ma o kahi pale kūwaho.Aia kekahi hōʻailona Power Good (PG) ma ka hāmeʻa e hōʻike ana i ka wā e hoʻohuli piha ʻia ai ka MOSFET nui, hiki ke hoʻohana ʻia e hiki ai ke hoʻouka i lalo. Hele mai nā mea ʻelua TPS22992x me ka thermalshutdown e hōʻoia i ka palekana i nā wahi wela kiʻekiʻe.Hoʻohui pū ka polokalamu TPS22992S i ka pale o kēia manawa, e pale ana i ka pōʻino o ka hāmeʻa inā pōkole ka hopena i ka honua i ka wā o ka hana a i ʻole ka hoʻomaka ʻana. .Loaʻa ʻia ka hāmeʻa TPS22992 ma kahi 1.5 × 1.25 mm, 0.5-mm pitch, 8-pinWQFN pūʻolo kahi e makemake ʻia ai kahi pine pine ākea.
Hōʻike ʻia nā mea hana ʻelua no ka hana ʻana ma luna o ka pae wela o ka ea manuahi o -40°C a i +125°C.
