MAX3355E
MAX3355E is 15kV ESD-Protected USB On-the-Go Charge Pump and Comparators manufactured by Maxim Integrated.
Description
The MAX3355E integrates a charge pump and parators to enable a system with an integrated USB onthe-go (OTG) dual-role transceiver to function as a USB OTG dual-role device. USB OTG facilitates the direct connection of peripherals and mobile devices such as PDAs, cellular phones, MP3 players, and digital cameras to one another without a host PC. .. The MAX3355E’s internal charge pump supplies VBUS power and signaling that is required by the transceiver as defined in On-the-Go Supplement to the USB 2.0 Specification, Revision 1.0. The MAX3355E features
ID detection and internal parators for monitoring VBUS. The VBUS status outputs are used during negotiation for the USB according to the session request protocol (SRP) and host negotiation protocol (HNP). The MAX3355E operates with logic supply voltages (VL) as low as 1.65V, ensuring patibility with lowvoltage ASICs. The device also features a logic-selectable 1µA shutdown mode. The MAX3355E has built-in ±15k V ESD-protection circuitry to protect the VBUS and ID_IN pins. The device is available in a miniature 4 x 3 chip-scale package (UCSP), as well as a 14-pin TSSOP package, and is specified for operation over the -40°C to +85°C extended temperature range.
Features o Guaranteed 8m A (min) VBUS Charge-Pump Output o ±15k V ESD Protection on VBUS and ID_IN o Up to +6.0V Backdrive Capability for VBUS o +2.6V to +5.5V Operating Voltage Range o VL Operates Down to +1.65V o Guaranteed VBUS Input Impedance When Not Driven o Automatic CLOAD Detection o parators for Host Negotiation Protocol o ID_IN Detection o Available in 4 x 3 UCSP or 14-Pin TSSOP Package
