SImproved Charger Interoperability USB CDP Emulation in S0 State Meets New USB Battery Charging (BC) Revision 1.2 Specification Backward Compatible with Previous USB BC Revisions Meets China YD/T1591-2009 Charging Specification Supports Standby Mode Charging for Apple and BC Revision 1.2-Compatible Devices The devices support pass-through mode and auto mode. In charging downstream port (CDP) pass-through mode, the devices emulate the CDP function while supporting normal USB traffic. The MAX14600/MAX14603/MAX14605 have a pFET open-drain output (CEN), and the MAX14601/ MAX14604 have an nFET open-drain output (CEN) to restart the peripheral connected to the USB host. All the devices support the CDP and standard downstream port (SDP) charging during the active state (S0) and support the dedicated charging port (DCP) charging during the standby state (S3/S4/S5). The MAX14603/ MAX14604/MAX14605 support remote wake-up in standby mode. The MAX14602/MAX14605 offer backwardcompatible CDP emulation upgrade to the MAX14566E. The MAX14600–MAX14605 are available in an 8-pin (2mm x 2mm) TDFN package, and are specified over the -40NC to +85NC extended temperature range.

These Hi-Speed USB switches feature low 4pF (typ) on-capacitance and low 4I (typ) on-resistance. DP and DM can handle signals between 0V and 6V with any supply voltage. Resistor-Dividers The MAX14600–MAX14605 family features an internal resistor-divider for biasing data lines to provide support for Apple-compliant devices. When the MAX14600– MAX14605 family is not operated with the resistor-divider, the device disconnects the resistor-dividers from the supply voltage to minimize supply current requirements. The resistor-dividers are not connected in pass-through mode. Switch Control The MAX14600–MAX14605 family features dual digital inputs, CB0 and CB1, for mode selection. For the MAX14600/MAX14601/MAX14603/MAX14604, connect CB0 and CB1 to a logic-level low voltage for autodetection charger mode (AM). Change only CB1 to a logic-level high for forced dedicated charger mode (FM). Change only CB1 to a logic-level low for normal highspeed pass-through mode (PM). Connect CB0 and CB1 to a logic-level high for high-speed pass-through mode with CDP emulation (CM). See Table 1. In CDP emulation mode, the peripheral device with CDP detection capability draws the charging current up to 1.5A immediately without USB enumeration. The MAX14602/MAX14605 have CB0 digital input control only (Table 2). The MAX14602/MAX14605 are pin-to-pin compatible with the MAX14566E, and CB0 and CB1 are connected together internally, which makes these devices easy upgrades for CDP emulation. Table 1.

Both CB0 and CB1 must be set low to activate autodetection charger mode. The MAX14600–MAX14605 family features an auto current-limit switch-control output. This feature resets the peripheral connected to VBUS in the event the USB host switches to or from standby mode. CEN or CEN provide a 2s (typ) pulse on the rising or falling edge of CB0 (Figure 4 and Figure 5.) With the MAX14603/MAX14604/ MAX14605, the auto peripheral reset is suspended in case of CB0 and CB1 transition from 11 to 00 as long as the peripheral remains connected. See the Remote Wake-Up Support section for more information. In autodetection charger mode, the device monitors the voltages at DM and DP to determine the type of device attached. If the voltage at DM is 2.05V (typ) or higher and the voltage at DP is 2.3V (typ) or lower, the voltage stays unchanged. If the voltage at DM is forced below the 2.05V (typ) threshold, the internal switch disconnects DM and DP from the resistor-divider and DP and DM are shorted together for dedicated charging mode. Also, if the voltage at DP is forced higher than the 2.3V (typ) threshold, the internal switch disconnects DM and DP from the resistor-divider and DP and DM are shorted together for dedicated charging mode. USB Pass-Through Mode with CDP Emulation The MAX14600–MAX14605 family features a passthrough mode with CDP emulation. This is to support the higher charging current capability during the passthrough mode in normal USB operation (S0 state). The peripheral device equipped with CDP detection capability could draw a charging current as defined Once the charging voltage is removed, the short between DP and DM is disconnected for normal operation.

System memory context is maintained, and all other system context is lost. S4 Hibernate. Platform context is maintained. S5 Soft off. in USB Battery Charger Specification 1.2 when the charging host supports the CDP mode. This is a useful feature since most host USB transceivers do not have the CDP function. Table 3 shows the different power states of S0–S5. Bus Voltage Discharge The MAX14601/MAX14604 auto current-limit switchcontrol output can be used to discharge the VBUS during VBUS reset. When the system controls the current limit switch for VBUS toggle, the output capacitor can be discharged slowly depending upon the load. If fast discharge of the VBUS is desired, the CEN output can be used to discharge the VBUS (Figure 6.) Data Contact Detect Support The MAX14600–MAX14605 family support USB devices that require detecting the USB data lines prior to charging. When a USB Revision 1.2-compliant device is attached, the USB data lines DP and DM are shorted together. The short remains until it is detected by the USB device. This feature guarantees appropriate charger detection if a USB Revision 1.2-compliant device is attached. The autodetection charger mode is activated after the data contact detect is established. CB0 and CB1 must be set low to activate data contact detect support. ���������������������������������������������������������������� Maxim Integrated Products 13 MAX14600–MAX14605 USB Host Charger Identification/Adapter Emulators USB TRANSCEIVER TDM TDP TDM TDP VCC 0.1µF GND DP D+ DM D- USB CONNECTION VBUS MAX14601 MAX14604 150µF VBUS VCC CURRENT-LIMIT SWITCH EN +5V POWER SUPPLY 1kΩ CEN GND CB0 PS EN PM/AM CB1 CM/FM SYSTEM CONTROL Figure 6. MAX14601/MAX14604 VBUS Discharge Circuit Remote Wake-Up Support The MAX14603/MAX14604/MAX14605 feature remote wake-up if pass-through mode with CDP emulation is used prior to transitioning to auto mode in standby state (S3). If the peripheral device is connected and remains in the USB port during S0 state, the MAX14600 maintains the pass-through mode until it is removed. If this feature is not needed, such as in battery-powered mode, the embedded control could cancel the remote wake-up by toggling the VBUS as it moves into the standby state. Backward Compatibility The MAX14602/MAX14605 offer easy backward-compatible CDP emulation upgrade to the MAX14566E. ESD Test Conditions ESD performance depends on a variety of conditions. Contact Maxim for a reliability report that documents test methodology and results. Extended ESD Protection (Human Body Model) ESD-protection structures are incorporated on all pins to protect against electrostatic discharges up to Q2kV (Human Body Model) encountered during handling and assembly. The ESD structures withstand high ESD both in normal operation and when the device is powered down. After an ESD event, the device continues to function without latchup (Figure 7a and Figure 7b). ���������������������������������������������������������������� Maxim Integrated Products 14 MAX14600–MAX14605 USB Host Charger Identification/Adapter Emulators RC 1MΩ RD 1.5kΩ CHARGE-CURRENTLIMIT RESISTOR DISCHARGE RESISTANCE HIGHVOLTAGE DC SOURCE CS 100pF STORAGE CAPACITOR IPEAK (AMPS) DEVICE UNDER TEST PEAK-TO-PEAK RINGING (NOT DRAWN TO SCALE) Ir 100% 90% 36.8% 10% 0 Figure 7a.
