Board overview
The TWR-SB0410-36EVB is a tower peripheral module that exercises valve control functions on SoC products based on the Tower
System. The Tower System acts as a debug and communication port for the PC being used to debug/download programs from the Kinetis
Design Studio/CodeWarrior system.

Description
Features
MC34SB0410
Quad Valve Controller System on Chip
Control Features
• Operating voltage up to 36 V
• Four low-side drivers regulate up to 2.25 A
• ± 2.0% precision reachable with calibration or four low-side drivers PWM up to 5 kHz with
a maximum current capability up to 5.0 A
• All low-side drivers are integrated to save PCB space
• One high-side pre-driver for DC Motor Control (up to 16 kHz)
• ADC can monitor external or internal signals to enhance the control unit safety level
• Only one SPI is needed to control the device
• Only one SPI access to write the current or a PWM command is needed
• MCU does not need to generate PWM signals at high frequency
Safety Features
• Undervoltage, overvoltage clock fail detection
• Open load, short circuit, overtemperature detection on each low-side
• V
