    TLS850F0TAV33 Linear Regulator with Watchdog


    We are using the TLS850F0TAV33 regulator in an ECU design for automotive. An option to disable the watchdog of the TLS850F0TAV33, for the microcontroller starting or in a
    special mode, is the Watchdog deactivation by WI, settting a voltage between 1.15V 1.4V at input WI (Watchdog Input).
    We have designed a solution with a voltage divider, a 3-state buffer and a flip-flop but would like to know if there is any related application note.

    You know, the watchdog should not be dis abled in normal operation mode when running the application.The WD ensures the safe operation, but as you mentioned the WD can be deactivated with a voltage level 1.15V..1.4V at Vi> 4.6V and VQnom=3.3V at the WI pin.
    Regrettably, there is no AppNote for the deactivation and no recommendation for the needed circuitry available. But this and the timing of the WD signal and other behaviour of the WD function is adequately described in the datasheet in the sections "5.9 Standard Watchdog" and "5.10 Typical Performance Characteristics Standard Watchdog".

    The output voltage is supervised via the Reset characteristic, which include Undervoltage Reset,behind schedule Reset at strength-On and an adjustable decrease Reset.I'm working in write my essay carrier and do your paper work on time in spite of the persistent time lack. Right here you can also discover a expert to do thesis papers for me on time and supply with the alternative writing solutions in case you need a few. Writing, enhancing, and formatting troubles can be easily resolved with the help of the unique on-line writing team from this is the service you positive gonna like as it offers the writers
