±15kV ESD-Protected USB On-the-Go
Charge Pump and Comparators in UCSP
General Description
The MAX3355E integrates a charge pump and com-
parators 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 cam-
eras to one another without a host PC.
www.DataSheeTth4eU.cMoAmX3355E’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 comparators for monitoring
VBUS. The VBUS status outputs are used during negoti-
ation for the USB according to the session request pro-
tocol (SRP) and host negotiation protocol (HNP).
The MAX3355E operates with logic supply voltages
(VL) as low as 1.65V, ensuring compatibility with low-
voltage ASICs. The device also features a logic-selec-
table 1µA shutdown mode.
The MAX3355E has built-in ±15kV ESD-protection cir-
cuitry 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.
