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 R_ON 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.
