General Description
The MAX13037/MAX13038 automotive contact monitor
and level shifters monitor and debounce eight remote
mechanical switches and assert an interrupt (
INT) if a
switch changes state. The state of each switch is sam-
pled through an SPI interface by reading the status
register. 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 MAX13037/MAX13038 supply an adjustable wet-
ting current to each closed switch to clean mechanical
switch contacts that are exposed to adverse conditions.
The MAX13037/MAX13038 feature a low dropout (LDO)
linear regulator capable of supplying up to 150mA of
current. The MAX13037 LDO has an output voltage of
+5V, whereas the MAX13038 has an output voltage of
+3.3V. The MAX13037/MAX13038 also feature a watch-
dog timer and an open-drain reset output with
adjustable timing.
The MAX13037/MAX13038 operate with a +6V to +26V
battery voltage applied to BAT. The MAX13037/
MAX13038 are available in a 6mm x 6mm, 36-pin TQFN
package and operate over the automotive -40°C to
+125°C temperature range.
