MAX3450E/MAX3451E/MAX3452E 19-2843 Rev 2 10/08 15kV ESD-Protected USB Transceivers General Description Features The MAX3450E/MAX3451E/MAX3452E USB-compliant 15kV ESD Protection on D+ and D- transceivers interface low-voltage ASICs with USB Combined VP and VM Inputs/Outputs devices. The devices fully comply with USB 1.1 and USB 2.0 when operating at full (12Mbps) and low +1.65V to +3.6V V Logic Supply Input for L (1.5Mbps) speeds. The MAX3450E/MAX3451E/ Interfacing with Low-Voltage ASICs MAX3452E operate with V as low as +1.65V, ensuring L Enumerate Input Function (MAX3451E) compatibility with low-voltage ASICs. The MAX3450E/MAX3451E/MAX3452E feature a logic- Powered from Li+ Battery as Low as +3.1V selectable suspend mode that reduces current con- (MAX3450E and MAX3451E) sumption to less than 40A. Integrated 15kV ESD V Detection (MAX3452E) BUS protection protects the USB D+ and D- bidirectional bus connections. The MAX3450E is pin compatible with Pin Compatible with Micrel MIC2550A (MAX3450E) Micrels MIC2550A. The MAX3451E features an internal Internal D+ or D- Pullup Resistor (MAX3451E) 1.5k USB pullup resistor and an enumeration function that allows devices to logically disconnect while No Power-Supply Sequencing Required plugged in. The MAX3452E provides a push-pull bus- detect (BD) output that asserts high when V is BUS greater than +4.0V. Ordering Information The MAX3450E/MAX3451E/MAX3452E operate over the PART PIN-PACKAGE TOP MARK -40C to +85C extended temperature range and are MAX3450EEUD+ 14 TSSOP available in 14-pin TSSOP and 3mm x 3mm 16-pin Thin QFN packages.
