Product type & package table Product type Package Marking TLE92464EDHP PG-DSO-36 Dual-Gauge (300 mil) TLE92464EDHP Description The TLE92464EDHP is a flexible, monolithic solenoid driver IC designed for the control of linear solenoids in automatic transmissions, electronic stability control, active suspension and e-Axle applications. The TLE92464EDHP is a four channel low-side solenoid driver IC with high current accuracy. The device provides an inital current accuracy of less than 3 mA up to 1200 mA current range. Including life time, the current accuracy is less than 0.8% up to 1200 mA. Over the full temperature, battery and current range (1500 mA in single channel mode, 2700 mA in parallel channel mode) the control error is less than 1%. The device includes the drive transistors and the current sensing resistors to minimize the number of external components. Target currents from 0 to 1500 mA can be programmed with a resolution of 15 bit. The device supports dither currents up to 1800 mA. The dither generator superimposes a triangular or trapezoidal waveform with programmable amplitude, frequency and shape on the programmed current setpoint. A 32 bit SPI interface is used to control the 4 channels and monitor the status of the diagnostic functions. The SPI communication is secured with an 8 bit CRC and a programmable timeout watchdog. An active low reset input (RESN) is used to disable all channels and reset the internal registers to the default values. An active high enable pin (EN) enables or disables the output channels without disabling the SPI interface. A fault output pin (FAULTN) signal can be used as external interrupt to the microcontroller whenever a fault is detected. Datasheet 2 Rev. 1.0 2021-12-15
