SBVS301B October 2016 – September 2021 TPS3850
PRODUCTION DATA
The TPS3850 features three options for setting the watchdog window: connecting a capacitor to the CWD pin, connecting a pullup resistor to VDD, and leaving the CWD pin unconnected. Figure 8-2 shows a schematic drawing of all three options. If this pin is connected to VDD through a 10-kΩ pullup resistor or left unconnected (high impedance), then the factory-programmed watchdog timeouts are enabled; see the Section 6.6 table. Otherwise, the watchdog timeout can be adjusted by placing a capacitor from the CWD pin to ground.
