*1: Output current rating may be limited by ambient temperature and heat sinking. Under any set of conditions, do not
exceed the specified.
*2: ESD caution: ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000V readily
accumulate on the human body and test equipment and can discharge without detection. Although this product
features proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high energy
electrostatic discharges. Therefore, proper ESD precautions are recommended to avoid performance degradation or
loss of functionality.

FP5501
Function Description
Device Operation
The FP5501 is a dual full-bridge low voltage motor driver capable of operating one stepper motor or up to two
dc motors. MOSFET output stages substantially reduce the voltage drop and the power dissipation of the
outputs of the FP5501 compared to typical drivers with bipolar transistors. Internal circuit protection includes
thermal shutdown with hysteresis and crossover current protection. The FP5501 is designed for portable
applications with a power-off (sleep mode) current of 100nA typical, and an operating voltage of 1.8V to 5.5V.
The FP5501 logic inputs are 3 to 5V logic compatible.
In conditions where the logic supply voltage drops below 1.8V, both the sink and the source voltage drop will
increase beyond the specified values. In extreme cases, no power will be delivered to the motors. However,
the device will not be damaged.
In stepping operation, the device can drive in either full- or half-step mode. The stepping mode is set by the
signal pattern on the Inx terminals, as shown in the stepping timing diagrams.
Sleep Mode
Pulling all inputs to 0.4V or less, sends the FP5501 to sleep mode, during which it draws 100nA typical.
Thermal Shutdown
The FP5501 will disable the outputs if the junction temperature reaches 150ºC. When thermal shutdown is
entered, after the junction temperature drops 15ºC, the outputs will be re-enabled.

The power dissipated by the IC varies widely with the supply voltage, the output current, and loading. It is
important to ensure the application does not exceed the allowable power dissipation of the IC package. The
recommended motor driver power dissipation versus temperature is depicted as follows:
