General Description
The MAX6495–MAX6499 is a family of small, low-current, overvoltage-protection
circuits for high-voltage transient systems such as those found in automotive
and industrial applications. These devices monitor the input voltage and
control an external n-channel MOSFET switch to isolate the load at the output
during an input overvoltage condition. The MAX6495–MAX6499 operate over a wide
supply voltage range from +5.5V to +72V.
The gate of the n-channel MOSFET is driven high while the monitored input is
below the user-adjustable over voltage threshold. An integrated charge-pump
circuit provides a 10V gate-to-source voltage to fully enhance the n-channel
MOSFET. When the input voltage exceeds the user-adjusted overvoltage
threshold, the gate of the MOSFET is quickly pulled low, disconnect ing the
load from the input. In some applications, dis connecting the output from the
load is not desirable. In these cases, the protection circuit can be
configured to act as a voltage limiter where the GATE output saw tooths to
limit the voltage to the load (MAX6495/MAX6496/MAX6499).
The MAX6496 supports lower input voltages and reduces power loss by replacing
the external reverse battery diode with an external series p-channel MOSFET.
The MAX6496 generates the proper bias voltage to ensure that the p-channel
MOSFET is on during normal operations. The gate-to-source voltage is clamped
during load-dump conditions, and the p-channel MOSFET is off during reverse-
battery conditions.
The MAX6497/MAX6498 feature an open-drain, undedicated comparator that
notifies the system if the output falls below the programmed threshold. The
MAX6497 keeps the MOSFET switch latched off until either the input power or
the SHDN pin is cycled. The MAX6498 will autoretry when VOVSET falls below
130mV.
These devices are available in small, thermally enhanced, 6-pin and 8-pin TDFN
packages and are fully specified from -40°C to +125°C.
