FP5502 is a micro-actuator driver IC with miniature package (SOT-23-6).
It is one channel low voltage
bi-directional motor driver IC.
The design is optimal for driving different type micro-actuator, such as voice coil
motor, piezo-actuator, or other DC motor actuators.
It is suitable for camera module application or other
MOSFET output stages substantially to reduce the voltage drop and the power dissipation of
the outputs of the FP5502 compared to typical drivers with bipolar transistors.
Internal circuit protection includes thermal shutdown with hysteresis and crossover current protection.
FP5502 is designed for portable applications with a power-off (sleep mode) current of 100nA typical, and an
operating voltage of 1.8 to 5.5.
FP5502 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.
the device will not be damaged.
Pulling all inputs to 0.4V or less drives the FP5502 to sleep mode.
And it will draw 100nA typical during sleep
The FP5502 will disable the outputs if the junction temperature reaches 150ºC.
When it enters thermal
shutdown, after the junction temperature drops 15ºC, the outputs will be re-enabled
