Shenzhen Mingjiada Electronics Co., Ltd. supply STMicroelectronics L9305EP Gate Driver Automotive 4-channel Valve Driver, brand new original, quality assurance, welcome to call!

Device Description

The L9305EP is a configurable monolithic solenoid driver IC designed to control linear solenoids in automatic transmission, electronic stability control and active suspension applications. The four channels can be configured in any combination as low or high voltage side drivers. The device includes power transistors, recirculation transistors, and current sensing for both power and recirculation transistors. This structure ensures redundancy in current measurement for each channel.

The regulated currents are programmable from 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 a configurable jitter modulation on the setpoint current.

A 32-bit CRC-protected SPI interface is used to configure and control all channels and provide status feedback for all diagnostic functions. Active-low reset input RESN is used to disable all channels and reset internal registers to default values. the EN_DR pin and integrated fail-safe pre-driver provide a safe enable path. An isolated redundant safe shutdown path ensures that critical internal faults disable the fail-safe pre-driver. The active-high enable pin EN_DR is used to enable or disable operation of all channels. When the EN_DR pin is low, all channels are disabled. The fault output pin is used to issue an external interrupt to the microcontroller when a fault is detected. Users can map specific faults to the FAULTn pin according to their specific system requirements.
