6 / 13 page XR 22414 6/13 REV1A Pin Number Pin Name Type Description 32 VCC33 PWR 3.3V power input 33 GND PWR Ground 34 EXT_RST# I External reset input, active low. Must be asserted for a minimum of 10uS 35 VBUS_SENSE I Connect to VBUS from USB host. In self-powered mode, indicates presence of host VBUS power 36 BUS_PWR# I Bus power indicator, active low. For bus powered mode, connect to ground. For self powered mode, connect to logic ‘1’. 37 REG_EN# I Active low enable of internal 5V to 3.3V regulator. Connect to logic ‘1’ when XR22414 is powered by 3.3V. 38 VCC5 PWR 5V power to internal 5V to 3.3V regulator. When XR22414 is powered by 3.3V, VCC5 should not be connected to 5V, and REG_EN# should be tied to logic ‘1’. 39 3V3_OUT PWR 3.3V power output from internal 5V to 3.3V regulator, may be used to power VCC33 power inputs if enabled by REG_EN# pin. Must be decoupled with minimum of 10 uF. Leave unconnected if XR22414 is powered by external 3.3V. 40 TEST I Test mode enable. Tie to ground for normal device operation 41 VCC33 PWR 3.3V power input 42 LED_CTL I/O LED hub active indicator. May also be used in conjunction with port status LEDs. Refer to Figure 4. 43 LED1 I/O Port 1 LED Indicator. Max source current 3mA. May be used in conjunction with DRV pin. Refer to Figure 4. Connecting LED1 to ground marks downstream port 1 as non-removable device. 44 LED2 I/O Port 2 LED Indicator. Max source current 3mA. May be used in conjunction with DRV pin. Refer to Figure 4. Connecting LED2 to ground marks downstream port 2 as non-removable device. 45 LED3 I/O Port 3 LED Indicator. Max source current 3mA. May be used in conjunction with DRV pin. Refer to Figure 4. Connecting LED3 to ground marks downstream port 3 as non-removable device. 46 LED4 I/O Port 4 LED Indicator. Max source current 3mA. May be used in conjunction with DRV pin. Refer to Figure 4. Connecting LED4 to ground marks downstream port 4 as non-removable device. 47 PWR1# O Power enable for port 1 downstream device in individual power mode. Asserted if OVC1# input is asserted in individual or global power mode or XR22414 is not configured. Used as global power control pin if ganged power control mode is selected by connecting PWR4# to ground.. 48 OVC1# I Downstream port 1 over current indicator in individual current-sensing mode, active low. If PWR4# is tied to ground, this pin is a global over-current sense input. 49 CPad PWR Connect QFN package center pad to PCB ground plane with thermal vias. NOTE: Type: I = Input, O = Output, I/O = Input/Output, PWR = Power, OD = Open-Drain. |
