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.

1. Package option not yet available.

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.
