Freescale Semiconductor Technical Data Document Number: MC33287 Rev.
5.0, 2/2007 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 VBAT.
One sense input has a dedicated o
