The TLE9241QU is an integrated circuit (IC) for use in automatic transmission control modules
Two gate drive outputs are included for controlling a reverse polarity protected high-side switch typically used to switch off power to the control module while the module is in a sleep state. Two high-side gate drive channels are also included for controlling two “safety” switches. These switches are typically used to provide power to the transmission solenoids. The device also provides interfaces for eight two-wire Hall Effect sensors, four of which can be used with position sensors and four which can be used with either position or speed sensors
Summary of Features
Four input interfaces for two-wire Hall Effect position sensors − Short to supply protection − Overtemperature protection − Sensor state status available by SPI
Four input interfaces for two-wire Hall Effect speed sensors − Digital output for speed and direction sensing − Further features set see position sensors above
Two high-side gate drive channels − Short circuit protection − Programmable overcurrent threshold − Output state status available by SPI
A high-side gate drive channel for driving n-channel MOSFETs in anti-serial configuration − Reverse polarity protected power switch
Integrated charge pump
16 bit SPI interface
Green Product (RoHS-compliant)
Benefits
Compared to a discrete circuit solution ~40% less PCB area ~65% fewer components
Potential Applications
