♠ TPS7B63xx-Q1 300-mA, 40-V High-Voltge, Ultra-Low-Quiscent-Current Watchdog LDO
Kuzinhlelo zokusebenza ze-automotive microcontroller noma i-microprocessor power-supply, i-watchdog isetshenziselwa ukuqapha isimo sokusebenza se-microcontroller ukuze kuvinjelwe ukubaleka kwesofthiwe.I-watchdog kumele izimele ku-microcontroller ohlelweni oluthembekile.
I-TPS7B63xx-Q1 iwumndeni wezilawuli ze-300-mA watchdog low-dropout (LDOs) ezidizayinelwe ivoltheji yokusebenza efika ku-40 V, enamanje othulile okuvamile angu-19 µA kuphela ekulayisheni okulula.Amadivayisi ahlanganisa umsebenzi ohlelekayo wokukhetha i-watchdog yewindi noma i-watchdog evamile, ene-resistor yangaphandle ukusetha isikhathi se-watchdog phakathi kokunemba okungu-10%.
Iphinikhodi ye-PG kumadivayisi we-TPS7B63xx-Q1 ikhombisa lapho i-voltage ephumayo izinzile futhi ilawulwa.Isikhathi sokulibaziseka okuhle kwamandla kanye ne-power-good threshold ingalungiswa ngokukhetha izingxenye zangaphandle.Amadivayisi aphinde abe nokuvikela okuhlanganisiwe kwe-short-circuit kanye ne-overcurrent.
Inhlanganisela yezici ezinjalo yenza lawa madivayisi avumelane nezimo ikakhulukazi futhi afanele ukuhlinzeka nge-microcontroller ezinhlelweni zezimoto.
• I-AEC-Q100 ifanelekele izicelo zezimoto:
– Izinga lokushisa 1: -40°C kuya ku-125°C, TA
• Isilinganiso esiphezulu samanje: 300 mA
• 4-V ukuya ku-40-V ububanzi be-VIN input-voltage ububanzi obufika ku-45-V transients
• Okuphumayo okulungisiwe okungu-3.3-V no-5-V
• I-voltage ephezulu yokuyeka: 400 mV ku-300 mA
• Izinzile nge-capacitor ekhiphayo ebangeni elibanzi lamandla (4.7 µF kuya ku-500 µF) ne-ESR (0.001 Ω kuya ku-20 Ω)
• Umoya othule ophansi (I(Q)):
- <4 µA uma i-EN iphansi (imodi yokuvala shaqa)
- 19 µA ejwayelekile emithwalweni elula ene-WD_EN ephezulu (i-watchdog ikhubazekile)
• Ilungiselelwa inja yokubuka iwindi noma inja yokuqapha ejwayelekile
• Isilinganiso sewindi elivuliwe ukuze livaliwe liyalungiseka njengo-1:1 noma 8:1
• Isikhathi se-watchdog esilungiseka ngokugcwele (kusuka ku-10 ms ukuya ku-500 ms)
• Isikhathi esinembile sokuqapha esingu-10%.
