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 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.
Features
• Eight High-Voltage Sense Inputs
• Direct Interfacing to Microcontroller
• Two Current Limited Low-Side Drivers
• Drivers Internally Overvoltage Clamped and Thermally
Protected
• 55 µA Standby Current
• Pb-Free Packaging Designated by Suffix Code EG

Notes
1 With Serial Resistor ≥ 25 kΩ
2 ESD1 testing is performed in accordance with the Human Body Model (CZAP=100 pF, RZAP=1500 Ω), ESD2 testing is performed in
accordance with the Machine Model (CZAP=200 pF, RZAP=0 Ω).
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.
