SLVSGE8A november 2022 – june 2023 TPS35-Q1
PRODUCTION DATA
The watchdog timeout design requirement can be met either by using a fixed-timeout version of the TPS35-Q1 or by connecting a capacitor between the CWD pin and GND. The typical values can be met with preprogrammed fixed time options, hence a pinout offering fixed time options is selected. Please see the Timing Requirements for a list of fixed timeouts. If using the CWD feature, pinout A or B must be used; please refer to tWD Timer for instructions on how to program the timout period. The design requirement in this example is tWD = 1.6 s. This is one of the fixed timeout options offered by pinout C or D. Thus the possible variant option is narrowed down to TPS35Cx13KAxDDFRQ1.
