infineon 恒流源电源芯片简介Product Brief IFX52001EJ Constant Current Relay Driver Key Features Once mechanical relayswitches and electromagnetic actuators (also known as solenoids)are turned on, current must continuously flow through their coils (hold High coil activation current current) to keep them on. Low hold current Suited for both low- and The IFX52001EJ can reduce the hold current down to the necessary amount to keep the high-side switches coil on (40mA without EMI) a……
