CC_PHY Block Diagram [PORT_CONT] This block chose the port mode according to the setting from MCU. (DFP) Variable current source is connected to CC terminal. These currents of each mode are 80μA±20%: Default Current, 180μA±8%: Medium Current and 330μA±8%: High Current. (UFP) Pull-down resistor (Rd=5.1kΩ±10%) is connected to CC terminal. (DRP) Changing DFP and UFP is repeated frequently. [CC_DET] CC_DET has functions of “Attach / Detach Detection”, “Plug Orientation / Cable Twist Detection”, “Discovery and detect extension mode” and “USB Type-C VBUS Current Detection”. Attach / Detach is detected with monitoring voltage of CC terminal. When the voltage of CC terminal become under a threshold voltage at DFP, attach is detected. Oppositely, when the voltage of CC terminal become over a threshold voltage, detach is detected. When the voltage of CC terminal become over a threshold voltage at UFP, attach is detected. www.rohm.com © 2015 ROHM Co., Ltd. All rights reserved. TSZ22111 • 15 • 001 14/28 TSZ02201-0232AA000210 -1-2 16, Jul.2015, Rev.001 BM92T20MWV Plug orientation and cable twist is detected from the relationship of two CC terminals. Because only one wire is connected to Rd, the difference between two CC terminals is generated. UFP can detect the maximum current of the power source by monitoring the voltage of CC terminal. It is possible to detect extension mode because DFP can detect Ra at Attach / Detach detection. [UFP_CLAMP] 1.1V Clamp is used for UFP emulation at dead-battery condition. [VBUS_MONI] UFP detect Attach / Detach by existence of VBUS voltage. VBUSDET detects Attach when VBUS voltage over the threshold voltage. And it detects Detach when VBUS under the threshold voltage. [VCONNSW] VCONNSW is the power switch for VCONN source. It has OCP (1.3Atyp) function. [BB_PHY] If Type-C controller supports BBPD, CC terminal can output BBPD communication signal.

All rights reserved. TSZ22111 • 15 • 001 26/28 TSZ02201-0232AA000210 -1-2 16, Jul.2015, Rev.001 BM92T20MWV 9 Operational Notes (1) Reverse Connection of Power Supply Connecting the power supply in reverse polarity can damage the IC. Take precautions against reverse polarity when connecting the power supply, such as mounting an external diode between the power supply and the IC’s power supply pins. (2) Power Supply Lines Design the PCB layout pattern to provide low impedance supply lines. Separate the ground and supply lines of the digital and analog blocks to prevent noise in the ground and supply lines of the digital block from affecting the analog block. Furthermore, connect a capacitor to ground at all power supply pins. Consider the effect of temperature and aging on the capacitance value when using electrolytic capacitors. (3) Ground Voltage Ensure that no pins are at a voltage below that of the ground pin at any time, even during transient condition. (4) Ground Wiring Pattern When using both small-signal and large-current ground traces, the two ground traces should be routed separately but connected to a single ground at the reference point of the application board to avoid fluctuations in the small-signal ground caused by large currents. Also ensure that the ground traces of external components do not cause variations on the ground voltage. The ground lines must be as short and thick as possible to reduce line impedance. (5) Thermal Consideration Should by any chance the power dissipation rating be exceeded the rise in temperature of the chip may result in deterioration of the properties of the chip. In case of exceeding this absolute maximum rating, increase the board size and copper area to prevent exceeding the Pd rating. (6) Recommended Operating Conditions These conditions represent a range within which the expected characteristics of the IC can be approximately obtained. The electrical characteristics are guaranteed under the conditions of each parameter. (7) Inrush Current When power is first supplied to the IC, it is possible that the internal logic may be unstable and inrush current may flow instantaneously due to the internal powering sequence and delays, especially if the IC has more than one power supply. Therefore, give special consideration to power coupling capacitance, power wiring, width of ground wiring, and routing of connections. (8) Operation Under Strong Electromagnetic Field Operating the IC in the presence of a strong electromagnetic field may cause the IC to malfunction. (9) Testing on Application Boards When testing the IC on an application board, connecting a capacitor directly to a low-impedance output pin may subject the IC to stress. Always discharge capacitors completely after each process or step. The IC’s power supply should always be turned off completely before connecting or removing it from the test setup during the inspection process. To prevent damage from static discharge, ground the IC during assembly and use similar precautions during transport and storage. www.rohm.com © 2015 ROHM Co., Ltd. All rights reserved. TSZ22111 • 15 • 001 27/28 TSZ02201-0232AA000210 -1-2 16, Jul.2015, Rev.001 BM92T20MWV Operational Notes – continued (10) Inter-pin Short and Mounting Errors Ensure that the direction and position are correct when mounting the IC on the PCB. Incorrect mounting may result in damaging the IC. Avoid nearby pins being shorted to each other especially to ground, power supply and output pin. Inter-pin shorts could be due to many reasons such as metal particles, water droplets (in very humid environment) and unintentional solder bridge deposited in between pins during assembly to name a few. (11) Unused Input Pins Input pins of an IC are often connected to the gate of a MOS transistor. The gate has extremely high impedance and extremely low capacitance. If left unconnected, the electric field from the outside can easily charge it. The small charge acquired in this way is enough to produce a significant effect on the conduction through the transistor and cause unexpected operation of the IC. So unless otherwise specified, unused input pins should be connected to the power supply or ground line. (12) Regarding the Input Pin of the IC This monolithic IC contains P+ isolation and P substrate layers between adjacent elements in order to keep them isolated. P-N junctions are formed at the intersection of the P layers with the N layers of other elements, creating a parasitic diode or transistor. For example (refer to figure below): When GND > Pin A and GND > Pin B, the P-N junction operates as a parasitic diode. When GND > Pin B, the P-N junction operates as a parasitic transistor. Parasitic diodes inevitably occur in the structure of the IC. The operation of parasitic diodes can result in mutual interference among circuits, operational faults, or physical damage. Therefore, conditions that cause these diodes to operate, such as applying a voltage lower than the GND voltage to an input pin (and thus to the P substrate) should be avoided. Figure xx. Example of monolithic IC structure (13) Ceramic Capacitor When using a ceramic capacitor, determine the dielectric constant considering the change of capacitance with temperature and the decrease in nominal capacitance due to DC bias and others. (14) Area of Safe Operation (ASO) Operate the IC such that the output voltage, output current, and power dissipation are all within the Area of Safe Operation (ASO). (15) Over Current Protection Circuit (OCP) This IC incorporates an integrated overcurrent protection circuit that is activated when the load is shorted. This protection circuit is effective in preventing damage due to sudden and unexpected incidents. However, the IC should not be used in applications characterized by continuous operation or transitioning of the protection circuit. www.rohm.com © 2015 ROHM Co., Ltd. All rights reserved.
