The MAX3353E integrates a regulated charge pump, switchable pullup/pulldown resistors, and an I2C-compatible 2-wire serial interface. The device provides a detector to monitor ID status and operates with logic supply voltages (VL) between +1.65V and VCC and charge-pump supply voltages (V CC ) from +2.6V to +5.5V. The charge pump supplies an OTG-compatible output on VBUS while sourcing 8mA output current. The MAX3353E enables USB OTG communication between digital logic parts that cannot supply or tolerate the +5V VBUS levels that USB OTG requires. By controlling and measuring VBUS using internal comparators, this device supports USB OTG session request protocol (SRP) and host negotiation protocol (HNP). The MAX3353E has built-in 15kV ESD protection circuitry to guard VBUS, ID_IN, D+, and D-. The MAX3353E is available in a 5 x 4 chip-scale package (UCSPTM) and 16-pin TSSOP package.
