L9305EP规格书详情
Description
The L9305 is a configurable, monolithic solenoid driver IC designed for the control
of linear solenoids for automatic transmission, electronic stability control, and active
suspension applications. The four channels can be configured as either low side
or high side drivers in any combination. The device includes the power transistor,
recirculation transistor and current sensing for both the power and recirculation
transistor. This architecture guarantees redundancy of the current measurement for
each channel.
The regulated current is programmable in the range of 0-1.5 A (normal range), with a
resolution of 0.25 mA, or 0-2 A (extended range), with a resolution of 0.33 mA. The
user can superimpose configurable dither modulation over the set point current.
