3. Pin soldering temperature limit is for 10 seconds maximum duration. Not designed for immersion soldering. Exceeding these limits may cause malfunction or permanent damage to the device.
4. Freescale's Package Reflow capability meets Pb-free requirements for JEDEC standard J-STD-020C. For Peak Package Reflow Temperature and Moisture Sensitivity Levels (MSL), Go to www.freescale.com, search by part number [e.g. remove prefixes/suffixes and enter the core ID to view all orderable parts. (i.e. MC33xxxD enter 33xxx), and review parametrics.


Description

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 independent overtemperature shutdown and diagnostic reporting
