ZHCSI93D May 2018 – October 2022 TPS65987D
PRODUCTION DATA
The battery charger (BC1.2) block integrates circuitry to detect when the connected entity on the USB D+/D– pins is a BC1.2 compliant charger, as well as advertise BC1.2 charging capabilities to connected devices. To enable the required detection and advertisement mechanisms, the block integrates various voltage sources, currents, and resistances. Figure 8-18 shows the connection of these elements to the TPS65987D C_USB_P and C_USB_N pins.
The pull-up and pull-down resistors required by the USB2 standard for a USB host or device are not provided by the TPS65987D and must be provided externally to the device in final applications.
