The MAX4864L/MAX4865L/MAX4866L/MAX4867 over-
voltage protection controllers protect low-voltage sys-
tems 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 inter-
nal 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-current standby mode (8.5µA). Also in
shutdown (EN set to logic-high), the current is reduced fur-
ther (0.4µA). The MAX4864L/MAX4865L/MAX4866L have
a +2.85V UVLO threshold, and the MAX4867 has a +2.5V
UVLO threshold.
In addition, a ±15kV ESD protection is provided to the
input when bypassed with a 1µF capacitor to ground. All
devices are offered in a small 6-pin SOT23 and a 6-pin,
2mm x 2mm µDFN package, and are specified for
operation over the -40°C to +85°C temperature range.
