Overvoltage Protection with USB Charger

Detection, LDO, and ESD Protection on D+/D-

Detailed 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 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 20ms debounce

time prevents false turn-on of the internal FET switch

during startup.
