Description

L7250 is a power IC for driving the SPINDLE and VCM motors, suitable for 5V & 12V application. The spindle system includes integrated power FETs which are driven using ST's Smoothdrive pseudo-sinusoidal commutation technology. The voice coil motor (VCM) system includes integrated power FETs, as well as ramp load and unload capability. Linear 3.3V and1.8V voltage regulators are included, as well as a negative regulator.

Power monitoring of VCC5, VCC12, and of the two positive voltage regulators is also included.L7250 uses a 3 wire serial interface: S_DATA, S_CLK and S_ENABLE
