Description
The TLE82453-3SA is a flexible, monolithic solenoid driver IC designed for the control of linear solenoids in
automatic transmission, electronic stability control, and active suspension applications. The three channels can
be used as either lowside or highside drivers in any combination. The device includes the drive transistor,
recirculation transistor, and current sensing resistor; minimizing the number of required external components.
This device is capable of regulating the average current flow in a load up to 1500 mA, depending on the dither
settings and the load characteristics, with 11 bits resolution. A triangular dither waveform generator, when
enabled, superimposes a triangular waveform with programmable amplitude and frequency on the programmed
current setpoint.
A 32 bit SPI interface is used to control thethree channels and to monitor the status of the diagnostic functions.
An active low reset input, RESN, is used to disable all of the channels and reset the internal registers to the default
values. An active high enable pin, EN, is used to enable or disable the operation of the output channels. When the
EN pin is low, the channels are disabled, and the SPI interface is fully functional. A fault output pin is provided to
generate a signal that can be used as an external interrupt to the microcontroller whenever a fault is detected.
