TLE92464ED

The Infineon TLE92464EDHP is a flexible, monolithic solenoid driver IC designed for controlling linear solenoids in automotive applications such as automatic transmissions and active suspension systems. This device integrates four independent low-side channels, each featuring MOSFETs with a low on-resistance of 115 mΩ. It provides precise current control with an accuracy of less than 1% and a programmable setpoint ranging from 0 mA to 1.5 A, supporting load currents up to 1.8 A with dither.

The TLE92464EDHP includes an integrated dither generator with programmable amplitude, frequency, and waveform, along with a 15-bit current setpoint resolution. Communication and control are managed via a 32-bit SPI interface with CRC and watchdog functions. Sophisticated protection mechanisms are built-in for each channel, including independent thermal shutdown, overtemperature protection, and diagnostics for open load, short circuit to ground, and overcurrent conditions.

Operating across a wide temperature range of -40°C to 175°C, this IC is qualified to AEC-Q100 Grade 0, making it suitable for demanding automotive environments. It is housed in a compact PG-DSO-36 package and is Pb-free and RoHS compliant. The device is also an ISO 26262 Safety Element out of Context for safety requirements up to ASIL C.
