The MAX3355E is a USB OTG dual-role device from MAXIM that 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.
The MAX3355E integrates a charge pump and comparators to enable USB On‑the‑Go (OTG) dual‑role operation. It supplies VBUS power with a guaranteed 8 mA output, provides ID detection, and includes internal comparators for host negotiation protocols. The device operates from a low logic supply voltage of 1.65 V and offers ±15 kV ESD protection on VBUS and ID_IN pins.
The part is available in a 4 × 3 UCSP package and a 14‑pin TSSOP package, and is specified for an extended temperature range of –40 °C to +85 °C. Typical application circuits, electrical characteristics, and layout recommendations are provided to aid designers in implementing the component in USB OTG systems.
