MAX14640MAX14644/MAX14651 USB Host Adapter Emulators General Description Benefits and Features The MAX14640MAX14644/MAX14651 are next-generation Improved Charger Interoperability USB 2.0 host charger adapter emulators that combine USB (CDP) Emulation USB Hi-Speed analog switches with a USB adapter Smart CDP emulator circuit. Foolproof CDP Meets New USB Battery Charging (BC) Revision 2 The MAX14640/MAX14651 feature an I C interface to fully 1.2 Specification configure the charging behavior with different address Backward-Compatible with Previous USB BC Revisions options. The MAX14641MAX14644 are controlled by Meets China YD/T1591-2009 Charging Specification two GPIO inputs (CB1/CB0) and support USB data and Supports Standby-Mode Charging for Apple BC automatic charger mode. In charging downstream port Revision 1.2 Compatible Devices (CDP) pass-through mode, the devices emulate the Provide Greater Application Flexibility CDP function while supporting normal USB traffic. The 2 I C Controls Multiple Modes (MAX14640/MAX14651) MAX14641/MAX14642/MAX14643 have a CEN output CB0 and CB1 Pins Control Multiple Automatic and for an active-high CLS enable input, and the MAX14644 Manual Charger States has a CEN output for an active-low CLS enable input to Enhance Performance with High Level of Integrated Features restart the peripheral connected to the USB host. Supports Remote Wakeup The MAX14640MAX14644/MAX14651 feature 2A high- Low-Capacitance USB 2.0 Hi-Speed Switch to current autodetect mode. The MAX14641 features 1A Change Charging Modes high-current forced mode instead of regular DCP mode. Automatic Current-Limit Switch Control 2 The MAX14640/MAX14651 can be configured through I C 15kV ESD Protection on DP/DM to support various dedicated charger modes such as DCP, Minimize PCB Area Apple 1A/2A forced, or Apple 1A/2A automatic mode. 2mm x 2mm, 8-Pin TDFN Package All the devices support CDP and standard downstream port (SDP) charging while in the active state (S0) and support Applications the dedicated charging port (DCP) charging while in the Laptop/Desktop Computers standby state (S3/S4/S5). All devices support low-speed USB Hubs remote wake-up by monitoring DM, and the MAX14642 / also supports remote wake-up in sleep mode (S3). Universal Chargers Including iPod /iPhone iPad The MAX14640MAX14644/MAX14651 are available in an Ordering Information and Typical Operating Circuit appear 8-pin (2mm x 2mm) TDFN-EP package and are specified at end of data sheet. over the -40NC to +85NC extended temperature range.
