ZHCSLZ8A September 2020 – August 2021 TPS65988DK
PRODUCTION DATA
The TPS65988DK 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.
