The MAX14529E/MAX14530E are overvoltage-protection
devices with USB charger detection, a low-dropout
(LDO) regulator, and ESD protection. These devices
feature a low 35mΩ (typ) RON internal FET switch and
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 prevent
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 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.
* Some packages have variations, listed on the drawing. "PkgCode/Variation" tells which variation the product uses. Note that "+", "#", "-" in the part number suffix describes RoHS status. Package drawings may show a different suffix character.
