High-Voltage, Overvoltage/Undervoltage,  
Protection Switch Controller  
General Description  
Features  
The MAX6399 is a small overvoltage and undervoltage  
protection circuit. The device can monitor a DC-DC out-  
put voltage and quickly disconnect the power source  
from the DC-DC input load when an overvoltage condi-  
tion occurs. A power-OK output signals when the  
DC-DC input voltage falls below an adjustable thresh-  
old. This controller architecture provides the ability to  
size the external n-channel MOSFET to meet specific  
load current requirements.  
♦ Wide Supply Voltage Range (5.75V to 72V)  
♦ Internal Charge Pump Ensures n-Channel  
MOSFET is Fully Enhanced During Normal  
Operation (V  
= 10V)  
GS  
♦ Fast GATE Shutoff During Overvoltage with 20mA  
Sink Capability  
♦ Latches Off External n-Channel MOSFET During  
High-Voltage Transients  
When the DC-DC monitored output voltage is below the  
user-adjustable overvoltage threshold, the GATE output  
of the MAX6399 goes high to enhance the n-channel  
MOSFET. The MAX6399 offers internal charge-pump  
circuitry that allows the GATE voltage to be 10V above  
♦ Adjustable DC-DC Input Undervoltage Threshold  
Power-OK Output  
♦ Adjustable DC-DC Output Overvoltage  
the input voltage (V  
= 10V) to fully enhance the  
Thresholds  
GS  
external n-channel MOSFET, thus minimizing the drain-  
to-source resistance.  
♦ Overtemperature Shutdown Protection  
♦ Fully Specified from -40°C to +125°C  
When the monitored output voltage rises above the  
user-adjusted overvoltage threshold, the GATE output  
rapidly pulls low to shut off the MOSFET. The MOSFET  
remains latched off until either the MAX6399 input  
power or SHDN input is cycled. The MAX6399 includes  
a logic-low shutdown input that disables the GATE. An  
internal overtemperature detector also disables the  
gate when the MAX6399 temperature reaches the ther-  
mal-shutdown threshold.
