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 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 independen
