MAX13037/MAX13038
Automotive Contact Monitor and
Level Shifters with LDO Regulator
______________________________________________________________________________________

Detailed 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. Any of the switch inputs can be
prohibited from asserting an interrupt. The switch
threshold levels are set to 50% of the voltage applied to
BATREF and all switch inputs feature a common
adjustable hysteresis, debounce time, and wetting cur-
rent. Two switch inputs (IN0, IN1) are programmable to
have direct outputs (DO0, DO1), useable for PWM or
other timing-based signals.
The MAX13037/MAX13038 feature an SPI interface to
monitor individual switch inputs and to configure inter-
rupt masking, hysteresis, and wetting current
enable/disable, switch configuration (battery-
connected or ground-connected), and scanning period.
The MAX13037/MAX13038 provide an internal low
dropout (LDO) linear regulator capable of supplying up
to 150mA. The LDO can be enabled or disabled
through two digital control inputs:
REGON and REGOFF.
A watchdog timer and power-on reset circuitry is provid-
ed on the MAX13037/MAX13038 to supervise external
microcontrollers (C).
The MAX13037/MAX13038 feature three modes of
operation: normal mode, scanning mode, and shut-
down mode. In normal mode, the part is fully functional
and internal sensing resistors are connected to all
switch inputs. In scanning mode, the sensing resistors
are connected for a finite duration to reduce power
consumption. In shutdown mode, all switch inputs are
high impedance and the internal LDO is switched off to
further reduce power consumption.
