The TLE8242-2L IC is an eight channel low-side constant current control pre-driver IC. Each channel can be configured to function either in direct PWM mode or in constant current mode by setting the appropriate CM bit in SPI message #1. | Summary of Features: Low side constant current control pre-driver integrated circuit; Four independent channels; Output current programmable with 11 bit resolution; Current range = 0 to 1.2A (typ.) with a 0.2Ohm sense resistor; Resolution = 0.78125 mA/bit (typ.) with a 0.2Ohm; sense resistor; /- 2% full scale error over temperature when autozero is used; Programmable PWM frequency via SPI from approximately 50 Hz to 4 KHz (typ.); Interface and Control; 32 Bit SPI (Serial Peripheral Interface) - Slave only; ENABLE pin to disable all channels or freeze all channels; Active low RESET_B pin resets internal registers to their default state and disables all channels.; Open drain FAULT pin can be programmed to transition low when various faults are detected.; 5.0V and 3.3V logic compatible I/O; Protection; Over current shutdown - monitored at POSx pin.; Programmable over current threshold; Programmable over current delay time; Programmable over current retry time; Battery pin (BAT) overvoltage shutdown | Benefits: Sense resistor can be scaled to expand solenoid current range above 1.2A; Minimal protection circuitry can be added in order to use the TLE8242-2L in 24V applications (commercial vehicles); Current profile detection feature can be use to determine movement of the solenoid armature | Target Applications: Variable Force Solenoids (e.g. automatic transmission solenoids); Other constant current solenoids; Idle Air Control; Exhaust Gas Recirculation; Vapor Management Valve; Suspension Control
