Block Diagram http://onsemi.com 2 NCN2500 PIN FUNCTION DESCRIPTION Pin 1 Symbol DSPD Function INPUT Description 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+ This pin interfaces the USB signals with the microcontroller digital line. The data present on the D+/D− pins are translated onto this signal. 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 mC to USB bus) OE = High Vp is a Plus receiver Output (from USB bus to mC) 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 mC to USB bus) OE = High Vm is a Minus receiver Output (from USB bus to mC) Digital input to control the VObus voltage. VObus connected to Vreg EN_VObus = Low VObus disconnected from Vreg (Hi Z) EN_VObus = High This pin carries the digital and USB ground level. High Quality PCB design shall be observed to avoid uncontrolled voltage spikes. 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 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 is connected to the USB Minus Data line I/O. The data direction depends upon the OE logic state. This pin is connected to the USB Plus Data line I/O The data direction depends upon the OE logic state. 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 W typical. This pin is connected to the USB port +Vcc supply voltage. This pin provides the interface power supply. The power source can be an external supply or can be derived from the USB + Vusb voltage. 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 2 3 RCV Vp OUTPUT I/O 4 Vm I/O 5 EN_VObus INPUT 6 7 GND SPND PWR INPUT 8 9 NC OE − INPUT 10 11 12 D− D+ Vreg I/O I/O PWR 13 VObus OUTPUT, PWR 14 15 16 Vusb Vcc EN_RPU PWR PWR INPUT http://onsemi.com 3 NCN2500 MAXIMUM RATINGS Rating Power Supply Voltage Digital Input Pins Digital Input Pins Digital Input Pins ESD Capability, HBM (Note 1) Vusb, D+, D−, GND Any Other Pins Machine Model, Any Pins QFN−16 Package Power Dissipation @ Tamb = +85°C Thermal Resistance, Junction−to−Air (RqJA) Operating Ambient Temperature Range Operating Junction Temperature Range Maximum Junction Temperature (Note 2) Storage Temperature Range Symbol Vcc Vind Vid Ibias VESD 10 2.0 200 PDS RqJA TA TJ TJmax Tsg 470 85 −40 to +85 −40 to +125 +150 −65 to +150 kV kV V mW °C/W °C °C °C °C Value 6.0 −0.5 V < Vin < Vcc + 0.5 V, but < 6.0 V −0.5 V < Vin < AGND + 0.5 V, but < 6.0 V −35 mA < Ibias < 35 mA Unit V V V mA Maximum ratings are those values beyond which device damage can occur. Maximum ratings applied to the device are individual stress limit values (not normal operating conditions) and are not valid simultaneously.
