TLE92464ED中文资料用于变速箱的恒流控制芯片数据手册Infineon规格书

描述 Description

The device controls the current through inductive loads with less than 1% error. Target currents can be programmed from 0 to 1500mA with a resolution of 15 bit. The TLE92464ED supports dither currents up to 1800mA. The dither generator superimposes a triangular or trapezoidal waveform with programmable amplitude and frequency on the programmed current setpoint.The device includes the drive transistors and the current sensing resistors to minimize the number of external components. TLE92464ED is ISO 26262 compliant and achieves safety level ASIL C.
