TLE72422GXUMA2

TLE72422GXUMA2 is a 4 channel fixed frequency constant current control 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. The application includes variable force solenoids (e.g. automatic transmission solenoids), other constant current solenoids, idle air control, exhaust gas recirculation, vapor management valve, suspension control.

• Low side constant current control pre-driver integrated circuit
• Four independent channels
• Programmable PWM frequency via SPI from approximately 50Hz to 4KHz (typ)
• Programmable KP and KI coefficients for the PI controller for each channel
• Programmed via the SPI interface, AEC qualified
• Dither for each channel can be enabled and programmed independently
• Phase delay time set via the SPI interface
• Synchronization initiated via signal at the PHASE_SYNC input pin
• Channels within one device and between multiple devices can be synchronized
• PG-DSO-28 package, junction temperature range from -40 to 150°C
