Block Diagram http://onsemi.com 2 8 NC 6 GND NCN2500 PIN FUNCTION DESCRIPTION Pin Symbol Function Description 1 DSPD INPUT 2 RCV OUTPUT This pin interfaces the USB signals with the microcontroller digital line. The data present on the D+/D− pins are translated onto this signal. 3 Vp I/O This pin, associated with Vm, is an I/O system interface signal depending upon the OE logic state: OE = Low Vp is a Plus driver Input (from C to USB bus) OE = High Vp is a Plus receiver Output (from USB bus to C) 4 Vm I/O This pin, associated with Vp, is an I/O system interface signal depending upon the OE logic state: OE = Low Vm is a Minus driver Input (from C to USB bus) OE = High Vm is a Minus receiver Output (from USB bus to C) 5 EN_VObus INPUT 6 GND PWR This pin carries the digital and USB ground level. High Quality PCB design shall be observed to avoid uncontrolled voltage spikes. 7 SPND INPUT The SPND digital signal (SUSPEND) selects the operation mode to reduce the power supply current. SPND = Low Normal operation SPND = High Suspend mode, no activity takes place 8 NC − 9 OE INPUT 10 D− I/O This pin is connected to the USB Minus Data line I/O. The data direction depends upon the OE logic state. 11 D+ I/O This pin is connected to the USB Plus Data line I/O The data direction depends upon the OE logic state. 12 Vreg PWR 13 VObus OUTPUT, PWR 14 Vusb PWR This pin is connected to the USB port +Vcc supply voltage. 15 Vcc PWR This pin provides the interface power supply. The power source can be an external supply or can be derived from the USB + Vusb voltage. 16 EN_RPU INPUT The DSPD logic level (Data Speed) activates the Low or the High speed operation on the USB port. DSPD = Low Low Speed, RPU1 and RPU2 connected to D− DSPD = High Full Speed, RPU1 and RPU2 connected to D+ Digital input to control the VObus voltage. VObus connected to Vreg EN_VObus = Low VObus disconnected from Vreg (Hi Z) EN_VObus = High No Connection, shall be neither grounded, nor connected to Vcc or Vbus. This pin activates the operating mode of the D−/D+ signals. Data are transmitted onto the USB bus OE = Low logic level Data are received from the USB bus OE = High logic level This pin provides a 3.3 V regulated voltage to supply the internal USB blocks and the external termination bias resistor. An external circuit can be connected to this LDO, assuming the current does not extend the maximum rating (50 mA). This pin connects the Vreg voltage to the 1.5 k external pullup resistor. The VObus voltage is controlled by the logic states present Pin 5. The RDSon of the internal PMOS device (reference S5 in the Block Diagram) is 10 typical. This pin activates or deactivate the internal RPU1 and RPU2 pullup resistors: EN_RPU = H RPU1 and RPU2 activated EN_RPU = L RPU1 and RPU2 deactivated http://onsemi.com 3 NCN2500 MAXIMUM RATINGS Symbol Value Unit Power Supply Voltage Rating Vcc 6.0 V Digital Input Pins Vind −0.5 V < Vin < Vcc + 0.5 V, but < 6.0 V V Digital Input Pins Vid −0.5 V < Vin < AGND + 0.5 V, but < 6.0 V V Digital Input Pins Ibias −35 mA < Ibias < 35 mA mA ESD Capability, HBM (Note 1) Vusb, D+, D−, GND Any Other Pins Machine Model, Any Pins VESD 10 2.0 200 kV kV V PDS RJA 470 85 mW °C/W Operating Ambient Temperature Range TA −40 to +85 °C Operating Junction Temperature Range TJ −40 to +125 °C Maximum Junction Temperature (Note 2) TJmax +150 °C Tsg −65 to +150 °C QFN−16 Package Power Dissipation @ Tamb = +85°C Thermal Resistance, Junction−to−Air (RJA) Storage Temperature Range Maximum ratings are those values beyond which device damage can occur.
