±15kV ESD-Protected USB On-the-Go Charge Pump and Comparators in UCSP

Active: In Production.

The MAX3355E integrates a charge pump and comparators to enable a system with an integrated USB On-the-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 V_BUS 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 comparators for monitoring V_BUS. The V_BUS 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 (V_L) as low as 1.65V, ensuring compatibility with low-voltage ASICs. The device also features a logic-selectable 1µA shutdown mode.

The MAX3355E has built-in ±15kV ESD-protection circuitry to protect the V_BUS 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.
