General Description

The MAX14529E/MAX14530E are overvoltage-protec-

tion devices with USB charger detection, a low-dropout

(LDO) regulator, and ESD protection. These devices

feature a low 35m

protect low-voltage systems against voltage faults up to

28V. When the input voltage exceeds the overvoltage

threshold, the internal FET switch is turned off to pre-

vent damage to the protected components.

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 sup-

plies 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.
