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 sampled 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 groundconnected or battery-connected switches.
