  • Single-channel smart high-side switch with a typical 9mΩ RON (TJ = 25°C)
  • Improve reliability through overcurrent protection:
    • Current limit threshold nominally at 20A
    • Current limiting (clamping) on reaching the threshold
  • Robust integrated output protection:
    • Integrated thermal protection
    • Protection against short to ground and supply
    • Automatic FET switch-on during reverse supply
    • Automatic shut off if loss of supply and ground occurs
    • Integrated output clamp to demagnetize inductive loads
    • Configurable fault handling
  • Configure the analog sense output to accurately measure:
    • Load current
    • Supply voltage
    • Device temperature
  • Provides FLT indication back to MCU
    • Detection of open load in off-state and short-to-GND

The TPS27SA08 device is a single-channel smart high-side switch intended for use with 24V supply systems. The device integrates robust protection and diagnostic features to establish output port protection even during harmful events like short circuits. The device protects against faults through a reliable current limit, which, depending on device variant, can be configured to react to an overcurrent event by either instantly turning the switch off or by regulating the output current at the set point (nominally 20A). The TPS27SA08 device also provides a high accuracy analog current sense that allows for improved diagnostics when driving varied load profiles. By reporting load current, device temperature, and supply voltage to a system MCU, the device enables predictive maintenance and load diagnostics that lengthen the system lifetime.

The TPS27SA08 device is available in a small 16-pin HTSSOP package which allows for reduced PCB footprint.
