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. FP5501-1.7-JAN-2013 8 fitipower integrated technology lnc.

Typical dual dc motor control application (timing chart) 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.
