L9305 jẹ atunto, awakọ solenoid monolithic IC ti a ṣe apẹrẹ fun iṣakoso awọn solenoids laini fun gbigbe laifọwọyi, iṣakoso iduroṣinṣin itanna, ati awọn ohun elo idadoro ti nṣiṣe lọwọ.Awọn ikanni mẹrin le tunto bi boya ẹgbẹ kekere tabi awọn awakọ ẹgbẹ giga ni eyikeyi apapo.Ẹrọ naa pẹlu transistor agbara, transistor recirculation ati imọ lọwọlọwọ fun agbara mejeeji ati transistor recirculation.Itumọ faaji yii ṣe iṣeduro apọju iwọn wiwọn lọwọlọwọ fun ikanni kọọkan.
Ilana ti a ṣe ilana jẹ siseto ni iwọn 0-1.5 A (iwọn deede), pẹlu ipinnu ti 0.25 mA, tabi 0-2 A (ibiti o gbooro sii), pẹlu ipinnu ti 0.33 mA.Olumulo naa le ṣe apọju iwọn atunto dither lori aaye ti o ṣeto lọwọlọwọ.
A 32-bit CRC ti o ni aabo ni wiwo SPI ni a lo fun iṣeto ni ati iṣakoso gbogbo awọn ikanni ati pese awọn esi ipo ti gbogbo awọn iṣẹ ayẹwo.Iṣagbewọle atunto kekere ti nṣiṣe lọwọ, RESN, ni a lo lati mu gbogbo awọn ikanni ṣiṣẹ ati tun awọn iforukọsilẹ inu si awọn iye aiyipada wọn.Ona ti o ni aabo ni a pese nipasẹ PIN EN_DR ati imudara Ikuna Ailewu Pre-awakọ.Ọna pipa-pa aabo aiṣedeede ti o ya sọtọ ṣe idaniloju pe awọn aṣiṣe inu ti o ṣe pataki mu awakọ iṣaaju ailewu kuna.Pinpin agbara giga ti nṣiṣe lọwọ, EN_DR, ni a lo lati mu ṣiṣẹ tabi mu iṣẹ ti gbogbo awọn ikanni ṣiṣẹ.Nigbati PIN EN_DR ba lọ silẹ, gbogbo awọn ikanni ti wa ni alaabo.A pese PIN abajade aṣiṣe ati pe o le ṣee lo lati ṣe idalọwọduro ita si microcontroller nigbakugba ti a ba rii aṣiṣe kan.Olumulo le ya awọn aṣiṣe kan pato si PIN FAULTn ti o da lori awọn ibeere eto wọn pato.
