Texas Instruments TPS281C30 High-Side Switch
Texas Instruments TPS281C30 High-Side Switch is a single-channel smart high-side switch designed to meet the requirements of industrial control systems. This switch operates at 60V tolerant, 30mΩ low on-resistance, and 6A continuous load current. The TPS281C30 switch protection features include thermal shutdown, output clamp, and current limit. This device operates at -40°C to 125°C temperature range. The TPS281C30 switch also provides an accurate load current sense that allows for improved load diagnostics, such as overload and open-load detection enabling better predictive maintenance. This high-side switch is used in digital output module, Safe Torque Off (STO), holding brake, and general resistive, inductive, and capacitive loads.
