Product Overview
The TPS65987 is a Texas Instruments USB Type-C PD controller for a single USB Type-C connector. It is USB PD 3.0 certified under USB-IF TID#: 1067 and is certified to the USB Type-C specification. The controller supports USB Type-C Power Delivery operation as both a source and a sink, with USB PD power paths rated up to 20 V and 5 A.
The device integrates two 20-V, 5-A source or sink load switches with 25 mΩ on resistance. When configured as a sink, the power paths provide reverse current protection, undervoltage protection, overvoltage protection, and slew rate control. When configured as a source, they provide undervoltage protection, overvoltage protection, and current limiting for inrush current protection.
TPS65987 is supplied from 3.3 V or a VBUS source and includes a 3.3 V dead-battery LDO output and a 1.8 V internal LDO output. It is offered in a 56-pin QFN (RSH56), 7.00 mm x 7.00 mm package and supports DisplayPort alternate mode, BC1.2 charging, GPIO control, and I2C control of external supplies, muxes, and peripherals.
