♠ TPS7B63xx-Q1 300-mA, 40-V High-Voltge, Ultra-Low-Quiscent-Cuiscent-Yangoku Watchdog LDO
Kwi-automotive microcontroller okanye i-microprocessor power-supply applications, i-watchdog isetyenziselwa ukubeka iliso kwisimo esisebenzayo se-microcontroller ukukhusela i-software.Umlindi kufuneka azimele kwi-microcontroller kwinkqubo ethembekileyo.
I-TPS7B63xx-Q1 lusapho lwe-300-mA watchdog low-dropout regulators (LDOs) eyenzelwe umbane osebenzayo ukuya kuthi ga kwi-40 V, kunye nomsinga othe cwaka oqhelekileyo we-19 µA kuphela kumthwalo olula.Izixhobo zidibanisa umsebenzi ocwangcisiweyo wokukhetha i-watchdog yefestile okanye i-watchdog eqhelekileyo, kunye ne-resistor yangaphandle ukuseta ixesha lokulinda ngaphakathi kwe-10% ukuchaneka.
I-PG pin kwi-TPS7B63xx-Q1 izixhobo zibonisa xa i-voltage ephumayo izinzile kwaye ilawulwa.Ixesha lokulibaziseka kwamandla kunye ne-power-good threshold inokulungiswa ngokukhetha amacandelo angaphandle.Izixhobo zikwabonisa i-short-circuit edibeneyo kunye nokukhusela okugqithisiweyo.
Ukudityaniswa kweempawu ezinjalo kwenza ezi zixhobo ziguquguquke kwaye zilungele ukubonelela nge-microcontroller kwizicelo zeemoto.
