5 / 20 page www.ti.com Power-Supply Input Options Electrostatic Discharge (ESD) TUSB2551 ADVANCED UNIVERSAL SERIAL BUS TRANSCEIVER SCES667 – FEBRUARY 2008 The TUSB2551 has two power-supply input options. • Internal regulator – V CC(5.0) is connected to 4 V to 5.5 V. The internal regulator is used to supply the internal circuitry with 3.3 V (nominal). Vreg(3.3) becomes a 3.3-V output reference. • Regulator bypass – V CC(5.0) and Vreg(3.3) are connected to the same supply. The internal regulator is bypassed, and the internal circuitry is supplied directly from the Vreg(3.3) power supply. The voltage range is 3 V to 3.6 V to comply with the USB specification. The supply-voltage range for each input option is specified in Table 3. Table 3. Power-Supply Input Options INPUT OPTION VCC(5.0) Vreg(3.3) VCC(I/O) Supply input for internal regulator Voltage-reference output Supply input for digital I/O pins Internal regualtor (4 V to 5.5 V) (3.3 V, 300 µA) (1.4 V to 3.6 V) Connected to Vreg(3.3) with Supply input Supply input for digital I/O pins Regulator bypass maximum voltage drop of 0.3 V (3 V to 3.6 V) (1.4 V to 3.6 V) (2.7 V to 3.6 V) PIN NAME ESD TYP UNIT IEC61000-4-2, Air-Gap Discharge ±9 D+, D–, VCC(5.0) IEC61000-4-2, Contact Discharge ±9 kV Human-Body Model ±15 All other pins Human-Body Model ±2 kV Copyright © 2008, Texas Instruments Incorporated Submit Documentation Feedback 5 Product Folder Link(s): TUSB2551 |
