MAX14529E/MAX14530E 19-4459 Rev 0 2/09 Overvoltage Protection with USB Charger Detection, LDO, and ESD Protection on D+/D- General Description Features The MAX14529E/MAX14530E are overvoltage-protec- Input Voltage Protection Up to 28V tion devices with USB charger detection, a low-dropout High-Current USB Charger Detection (LDO) regulator, and ESD protection. These devices 3.3V, 100mA LDO feature a low 35m (typ) R internal FET switch and ON protect low-voltage systems against voltage faults up to Preset Overvoltage Protection Trip Level 28V. When the input voltage exceeds the overvoltage 5.75V (MAX14529E) threshold, the internal FET switch is turned off to pre- 6.8V (MAX14530E) vent damage to the protected components. Integrated Low R 35m (typ) FET Switch ON The charger detection detects a short between the USB Low-Capacitance USB High-Speed Data Line ESD D+ and D- data lines. If the data lines are shorted Protection (3pF) together and a dedicated charger is attached, the 15kV Human Body Model (HBM) phone draws more than 500mA to charge the battery. 15kV IEC 61000-4-2 Air Gap The overvoltage thresholds (OVLO) are preset to 5.75V 8kV IEC 61000-4-2 Contact (MAX14529E) or 6.8V (MAX14530E). Thermal-Shutdown Protection The LDO output (LOUT) is powered from OUT and sup- 12-Bump, 1.5mm x 2mm WLP Package plies 3.3V to the USB transceiver. The LDO features a -40C to +85C Operating Temperature Range 100mA (min) current capability and low output noise. The MAX14529E/MAX14530E feature 15kV HBM ESD Ordering Information/ protection with low (3pF) capacitance suitable for Hi-Speed USB 2.0. Selector Guide Both devices are offered in a small 12-bump, 1.5mm x PIN- PART TOP MARK OVLO (V) 2mm WLP package and operate over the -40C to PACKAGE +85C extended temperature range.

Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability. ELECTRICAL CHARACTERISTICS (V = 2.2V to 28V, T = T to T , unless otherwise noted.
