Should internal supply voltage become lower than internal threshold VINT-Fail will reset order indicate undervoltage condition (VINT-UV). other settings also reset this condition. VINT-Fail feature also used give indication that system supply disconnected therefore pre-setting routine microcontroller started. When voltage falls below reset threshold voltage VRTx time duration longer than filter time reset output switched will released after programmable delay time (default setting PowerOn-Reset) when VRTx.

After above described delayed reset (LOW HIGH transition RESET pin) window watchdog circuit started opening long open window Standby Mode. long open window allows microcontroller initialization sequences then trigger watchdog SPI. Within long open window period watchdog trigger detected write access "window watchdog period field" within control word. trigger accepted when input becomes HIGH after transmission word. correct watchdog trigger results starting window watchdog opening closed window with width selected window watchdog period. This period, selected window watchdog timing field, programmable wide range. closed window followed open window with width selected period. microcontroller service watchdog periodically writing window watchdog timing field. This write access meet open window. correct watchdog service immediately results starting next closed window. Should trigger signal meet open window watchdog reset generated setting reset output low. Then watchdog again starts opening long open window. addition, "window watchdog reset flag" within monitor watchdog reset. fail safe reasons TLE7809G automatically switched Standby mode watchdog trigger failure occurs. This minimizes power consumption case permanent faulty microcontroller. This "window watchdog reset flag" will cleared access SPI. When entering power mode watchdog requested enabled bit. Stop Mode watchdog only turned once current consumption falls below "watchdog current threshold".

Side Switches
Side Switches
side switches have been designed drive relays, e.g. window lift applications. continuous output current dimensioned 300mA (each) maximum. Active Receive-Only mode side outputs switched off, respectively input bit. Protection against overcurrent, overtemperature overvoltage conditions integrated low-side drivers. case load current that exceeding overcurrent threshold both drivers switched-off after filter time. thermal protection circuit included well, switching-off drivers case overtemperature threshold reached. both cases diagnostic information updated accordingly interconnect pulled "low" internal cycle (see "SBC Oscillator" Page 36). drivers have re-activated command. overvoltage protection been implemented active clamping inductive loads preventing occurrence voltage peaks. Moreover switches automatically disabled when reset watchdog reset occurs. However, switches automatically switched case overvoltage condition, e.g. load dump. double-failure occurs same time causing overcurrent (OC) overtemperature (OT) condition, than turned order protect Note: case turned condition second turned automatically (bidirectional interconnect pulled "low"). also switched microcontroller pulling bi-directional interconnect "low" least internal cycle (see "SBC Oscillator" Page 36).

Supply Output Hall Sensor Supply
Supply Output Hall Sensor Supply
SUPPLY Output intended used Hall Sensor supply. Active Receive-Only mode this output switched off, respectively input bit. Note: SUPPLY Output needs turned-off prior entering Stop Mode command will inherit state" from previous operation mode. case entering Sleep Mode turned-off automatically. This output provides output voltage limitation protected against overcurrent overtemperature. protection mechanisms low-sides switches also apply this high-side switch. case overcurrent shutdown supply output re-activated command. order prevent unintended shut-down overcurrent situation when capacitive load connected, specified blanking time after switching-on been implemented applied directly after activation this output.

High-Side Switch Driver (HS-LED)
high side output HS_LED intended driving LEDs small lamps. This function wake-up function MON5 input realized same (MON5/HS_LED). Active Receive-Only mode high side output switched off, respectively input (automatically "off" Stop Mode). high-side driver protected against overcurrent overtemperature. HS-LED automatically disabled case undervoltage (Vbat-UV) overvoltage condition (Vbat-OV) only re-activated command. This HS-LED OV/UV feature disabled (see Table "General Integrated Switch Configuration" Page 21).
