Status
Active: In Production.
Description
The MAX13036 automotive contact monitor and level
shifter monitors and debounces eight remote mechanical
switches and asserts an interrupt (active-low 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 logic supply
input (VL) sets the interface voltage. The MAX13036 is
available in a 5mm x 5mm 28-pin TQFN package and
operates over the -40°C to +125°C temperature range.
