(1) VDD pin should monotonically reach 95% of its final value within supply ramp time. All VDD pins were tied together for this evaluation. For non-monotonic or slower power supply ramp, it is recommended to pull-down PDN pin until VDD pins have reached 95% of its final value. PDN pin has a 50 kΩ pullup resistor. When PDN pin cannot be actively controlled, TI recommends to add a capacitor to GND on PDN pin to delay the release of reset.
