Contact Monitor and Level Shifter  
General Description  
Features  
+6V to +26V Operating Voltage Range  
The MAX13036 contact monitor and level shifter monitors  
and debounces eight remote mechanical switches and  
asserts an interrupt (INT) if a switch changes state. The  
state of each switch is sampled through an SPI interface  
by reading the status register and any switch can be  
prohibited from asserting an interrupt by writing to the  
command register. Four of the switch inputs are intended  
for ground-connected switches (IN0–IN3), and the other  
four inputs (IN4–IN7), are programmable in groups of  
two for either ground-connected or battery-connected  
switches. Two switch inputs (IN0, IN1) have direct level-  
shifted outputs (DO0, DO1) to be used for PWM or other  
timing-based signals.

Switch input thresholds are set to 50% of the voltage  
applied to BATREF. The threshold hysteresis is set by  
connecting an external resistor from HYST to ground. The  
MAX13036 supplies an adjustable wetting current to each  
closed switch to clean mechanical switch contacts that  
are exposed to adverse conditions.

The MAX13036 operates with a +6V to +26V battery  
voltage applied to BAT. A separate +2.7V to +5.5V
