TPS272C45 Dual-Channel Smart High-Side Switches

Texas Instruments TPS272C45 Dual-Channel Smart High-Side Switches are designed to meet the requirements of industrial control systems. The low on-resistance R_DS(on) of 45mΩ) minimizes device power dissipation driving a wide range (100mA to 3A) of output load current. The device provides an additional low voltage supply (3.3V to 5V) input pin to minimize no-load power dissipation. The device integrates protection features such as thermal shut down, output clamp, and overcurrent limit. These features improve system robustness during fault events such as a short circuit.
