DESCRIPTION
The charger detection detects a short between the USB D+ and D- data lines. If the data lines are shorted together and a dedicated charger is attached, the phone draws more than 500mA to charge the battery. The overvoltage thresholds (OVLO) are preset to 5.75V (MAX14529E) or 6.8V (MAX14530E). The LDO output (LOUT) is powered from OUT and supplies 3.3V to the USB transceiver. The LDO features a 100mA (min) current capability and low output noise. The MAX14529E/MAX14530E feature ±15kV HBM ESD protection with low (3pF) capacitance suitable for Hi-Speed USB 2.0. Both devices are offered in a small 12-bump, 1.5mm x 2mm WLP package and operate over the -40°C to +85°C extended temperature range. PART FEATURES
