Power-up Procedure

The RT1716 supports DRP and Dead battery mode in this evaluation board. The followings explain the functions.

1. Insert 12V adapter and turn on the toggle switch. The 5V adapter and +3V3_DVDD LEDs wll light up. CC1 and CC2 will start DRP toggling.

2. If the RT1716 is attached as source, ie CC present Rp, source path will be on and output 5V at VBUS.

Pressing “PowerRoleSwap” button will execute power role swap. If sink side accepts, source path will be off, the RT1716 will swap to sink, sink path will be on, and there will be 5V at SinkVBUS.

After the RT1716 swaps to sink, pressing “SinkPDO” button will ask next PDO (PD_Object) from port partner.

3. If the RT1716 is attached as sink, ie CC present Rd, sink path will be on and there will be 5V at SinkVBUS.

Pressing “SinkPDO” button will ask next PDO (PD_Object) from port partner.

Pressing “PowerRoleSwap” button will execute power role swap. If source side accepts, sink path will be off, the RT1716 will swap to source, source path will be on, and there will be 5V at VBUS.

4. If 12V adapter is not inserted, CC1 and CC2 will present Rd. If source is inserted into Type-C receptacle, the whole EVB will be active. The sink path will be on and there will be 5V at SinkVBUS.

Pressing “SinkPDO” button will ask next PDO (PD_Object) from port partner.

Pressing “PowerRoleSwap” button will not execute power role swap because there is no adapter power.

Pressing “Reset” button will reset +3V3_DVDD. MCU and the RT1716 will be reseted.

Carefully inspect all the components used in the EVB according to the following Bill of Materials table, and then make sure all the components are undamaged and correctly installed. If there is any missing or damaged component, which may occur during transportation, please contact our distributors or e-mail us at evb_service@richtek.com.


Test Points

The EVB is provided with the test points and pin names listed in the table below.

Test Point/

Pin Name

Function

VBUS

5V as the RT1716 is souorce. 5V to 20V as the RT1716 is sink.

CC1

CC1 is used to establish and manage the Source-to-Sink connection.

CC2

CC2 is used to establish and manage the Source-to-Sink connection.

GND

Ground.

SinkVBUS

As the RT1716 is sink, sink path will turn on. The RT1716 will get power from port partner for system applications.

GPIO1~4

These four pins are used to control other functions in system for user.

UTX/URX

These two pins are used to trace log of MCU.

SDA/SCL

These two pins are I2C communication between the RT1716 and MCU.

ICPDA/ICPCK

These two pins are used to programming MCU.

1. The capacitance values of the input and output capacitors will influence the input and output voltage ripple.

2. MLCC capacitors have degrading capacitance at DC bias voltage, and especially smaller size MLCC capacitors will have much lower capacitance.
