4xConst.Freq.I-CtrlIC SO-28 SMD Description

The TLE7242-2G IC is a four channel low-side constant current control pre-driver IC. Each channel can be configured to function either in on/off mode or in constant current mode by setting the appropriate MODE bit in SPI message #7.

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 TLE7242-2G in 24V applications (commercial vehicles)

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
