Technical Data
Contact Monitoring and Dual
Low-Side Protected Driver
The 33287 interfaces between switch contacts and a
microcontroller. Eight switch-to-battery (or switch-to-ground) sense
monitor switch status. Additionally, two internal low-side switches are
available to control inductive or capacitive loads.
The 33287 has eight sense inputs (rated at 40 V) with thresholds
ratiometric to V
BAT
. One sense input has a dedicated output for direct
interfacing to the MCU and the remaining seven inputs are
multiplexed interfaced to the MCU.
The two low-side switch outputs are current limited to 535 mA and
internally clamped to 50 V. Outputs also have independent
overtemperature shutdown and diagnostic reporting.
