Q & A
- What is the data rate of the MAX3318EIPWR?
The MAX3318EIPWR operates at a data rate of 460 kbps
- What is the operating voltage range of the MAX3318EIPWR?
The device operates from a single 2.25-V to 3-V supply
- What level of ESD protection does the MAX3318EIPWR offer?
The device features ESD protection up to ±15 kV (Human-Body Model), ±8 kV (IEC 61000-4-2, Contact Discharge), and ±15 kV (IEC 61000-4-2, Air-Gap Discharge)
- How does the auto-power-down plus feature work?

- What is the purpose of the READY output?
The READY output indicates when the charge pump is regulating and the device is ready to begin transmitting
- How many capacitors are required for the charge pump?
The charge pump requires only four 0.1-μF capacitors
- What is the operating temperature range of the MAX3318EIPWR?
The operating temperature range is -40°C to 85°C
- In which applications is the MAX3318EIPWR commonly used?
The device is commonly used in battery-powered systems, PDAs, cellular phones, notebooks, hand-held equipment, and pagers
