Infineon Technologies AG Power - Automotive conventional powertrain ICs - Constant Current Control IC for Transmission - TLE92464EDHP TLE92464EDHP

Compared to the existing TLE92464ED, the TLE92464EDHP offers higher accuracy performances, in particular: <±3 mA up to 1200 mA initially <±0.8% up to 1200 mA including aging Target currents can be programmed from 0 to 1500mA with a resolution of 15 bits. The TLE92464EDHP 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. TLE92464EDHP is ISO 26262 compliant and achieves safety level ASIL Summary of Features High current control accuracy <±3 mA up to 1200 mA initially (TJ = -40 - 150°C, VBAT = 9 - 16 V) <±0.8% up to 1200 mA including aging (TJ = -40 - 150°C, VBAT = 9 - 16 V) <±1% up to 1500 mA including aging (TJ = -40 - 150°C, VBAT = 6 - 18 V) Four independent low side channels with integrated MOSFETs (RDSon = 115 mΩ) Programmable setpoint from 0mA to 1.5A Load current including dither 1.8A Current in parallel channel mode 2.7A Integrated dither generator with programmable amplitude, frequency, and waveform 15-bit current setpoint resolution Integrated sense resistor RSHUNT = 140 mΩ Excellent immunity to large load supply voltage changes Operation down to 3.5 V at VDD pin 32-bit SPI with 8 bit CRC and SPI watchdog Sophisticated protection and diagnostic functions for each channel in on and off state: Independent thermal shutdown for each channel Diagnostic Function (Open Load, Short Circuit Ground, Over Current) Voltage monitoring Overtemperature protection Two independent current feedback paths Integrated system clock with clock watchdog Temperature range -40°C to 175 °C Small power package PG-DSO-36-72 Green product (RoHS-compliant) Pb-free (RoHS-compliant) package AEC-Q100 Grade 0 qualified ISO 26262 Safety Element out of Context for safety requirements up to ASIL C Benefits Reduction of TCU calibration efforts saving cost and time Enables ASIL D on system level Full temp range up to 175°C +/- 1% Current Accuracy over lifetime (-40°C to 150°C) Excellent regulation performance for step responses Excellent Battery Ripple Rejection Ease of use due to the family concept with 6CH TLE92466ED device Same software and package as TLE92464ED and TLE92466ED enables maximal reuse Scalable solution Integrated Power Devices Minimizes number of components placement, simplifies PCB layout Enables current limitation, slew rate control, and thermal protection Improved Short-to-Battery performance Potential Applications Variable force solenoids (e.g. automatic transmission and e-Axle) Other constant current solenoids Idle air control Exhaust gas recirculation Vapor management valve Suspension control Applications Active suspension control Automotive body control module (BCM) Designers who used this product also designed with TLE75080-ESD | Multichannel SPI switches and controllers BTS70020-1ESP | PROFET™ +2 12V | automotive smart high-side switch BTS71220-4ESA | SPOC™ +2 | multichannel serial interface high-side power controller BTS7008-1EPP | PROFET™ +2 12V | automotive smart high-side switch IAUC60N04S6N050H | Automotive MOSFET IAUC45N04S6N070H | Automotive MOSFET BTN7030-1EPA | MOTIX™ single half-bridge ICs for BDC motors BTS71033-6ESA | SPOC™ +2 | multichannel serial interface high-side power controller IAUC120N04S6N010 | Automotive MOSFET TLE75080-ESD | Multichannel SPI switches and controllers BTS70020-1ESP | PROFET™ +2 12V | automotive smart high-side switch BTS71220-4ESA | SPOC™ +2 | multichannel serial interface high-side power controller BTS7008-1EPP | PROFET™ +2 12V | automotive smart high-side switch IAUC60N04S6N050H | Automotive MOSFET IAUC45N04S6N070H | Automotive MOSFET BTN7030-1EPA | MOTIX™ single half-bridge ICs for BDC motors BTS71033-6ESA | SPOC™ +2 | multichannel serial interface high-side power controller 1 2 3
