8 Channel, 2-A High-Side Driver Reference Design for Digital Output Modules


Design files


This eight-channel, parallel, 2-A, high-side, digital output reference design for factory automation applications like PLCs shows the diagnostic features and the power density of new Texas Instruments high-side driver components (such as TPS27S100). Each output can individually measure the output current in real time. This feature makes it possible to detect wire breaks and short circuits during operation. Modifications of the output load due to ageing or manipulation can be discovered as well.

  • Eight channel 24V high side switch digital output
  • 2A/channel 10A total per board fully protected
  • Output current test per channel (5mA accuracy)
  • Negative clamping voltage -30V (fast decay)
  • Power supply current limit and circuit breaker
  • Designed to comply with IEC61000-4-x
