Overview
DataSheet.
in 19-3582; Rev 1; 5/06 Overvoltage Protection Controllers with Reverse Polarity Protection General Description The MAX4864L/MAX4865L/MAX4866L/MAX4867/ MAX4865/MAX4866 overvoltage protection controllers protect low-voltage systems against high-voltage faults up to +28V, and negative voltages down to -28V.
These devices drive a low-cost complementary MOSFET.
If the input voltage exceeds the overvoltage threshold, these devices turn off the n-channel MOSFET to prevent damage to the protected components.
If the input voltage drops below ground, the devices turn off the p-channel MOSFET to prevent damage to the protected components.
An internal charge pump eliminates the need for external capacitors and drives the MOSFET GATEN for a simple, robust solution.
The overvoltage thresholds are preset to +7.
4V (MAX4864L), +6.
35V (MAX4865L), +5.
8V (MAX4866L), and +4.
65V (MAX4867).
When the input voltage drops below the undervoltage lockout (UVLO) threshold, the devices enter a low-curr...
