MC33887 Device Features
The MC33887 IC is able to control inductive loads with continuous DC load currents up to 5.0 A, and with
peak current active limiting between 5.2 A and 7.8 A. Output loads can be pulse width modulated (PWM) at
frequencies up to 10 kHz. The load current feedback feature provides a proportional constant-current output
(at 1/375th of the load current) suitable for monitoring by a microcontroller ’s A/D input. This feature
facilitates the design of closed-loop torque/speed control as well as open load detection. Additional device
features/characteristics include the following:

TTL/CMOS-compatible inputs
PWM frequencies up to 10 kHz
Active current limiting (regulation)
Fault status reporting
Sleep mode with current draw ≤ 0.50 μA (inputs floating or set to match default logic states)
Freescale analog ICs are manufactured using the SMARTMOS process, a combinational BiCMOS
manufacturing flow that integrates precision analog, power functions and dense CMOS logic together on a
single cost-effective die.
