MAX14529E - (MAX14529E / MAX14530E) Overvoltage Protection

General Description

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.

Key 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.
  • Input Voltage Protection Up to 28V.
  • High-Current USB Charger Detection.
  • 3.3V, 100mA LDO.
  • Preset Overvoltage Protection Trip Level 5.75V (MAX14529.

19-4459; Rev 0; 2/09 www.DataSheet4U.com Overvoltage Protection with USB Charger Detection, LDO, and ESD Protection on D+/DGeneral Description 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.
