4 Channel Fixed Frequency Constant Current Control IC

The TLE7242 2G IC is a four channel low-side constant current control predriver 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 .

Featurres:

• Low side constant current control pre-driver integrated circuit
• Four independent channels
• Output current programmable with 11 bit resolution
• Programmable PWM frequency via SPI from approximately 50 Hz to 4 KHz (typ)
• Programmable KP and KI coefficients for the PI controller for each channel
• Programmable Transient Mode of operation to reduce settling time when large changes in the current set point are commanded.
• Programmable superimposed dither.
• Programmable synchronization of the PWM control signals.
• Each channel can be configured to function as a simple on/off predriver or a constant current predriver via SPI
• Interface and control
• Protection
• Diagnostics
• Control loop monitor capabilities
• Required External Components:
• Green Product (RoHS compliant)
• AEC Qualified
