ZHCSJP1B May 2019 – October 2022 TPS65987DDJ
PRODUCTION DATA
The TPS65987DDJ has an integrated active pull-down on VBUS for transitioning from high voltage to VSAFE5V. When the high voltage switch is disabled and VBUS > VSAFE5V, an amplifier turns on a current source and pulls down on VBUS. The amplifier implements active slew rate control by adjusting the pull-down current to prevent the slew rate from exceeding specification. When VBUS falls to VSAFE5V, the pull-down is turned off.
