Texas Instruments TPS1HTC100-Q1 Single-Channel Smart High-Side Switch is a smart high-side switch with an integrated NMOS power FET and charge pump designed to meet the requirements of 24V automotive battery systems. The low RON (83mΩ) minimizes device power dissipation, driving a wide range of output load current up to 4A DC, and the 60V DC operating range improves system robustness. The device integrates protection features such as current limit, thermal shutdown, and output clamp. These features improve system robustness during fault events such as short circuits. TPS1HTC100-Q1 implements an adjustable current limiting circuit that enhances the system's reliability by minimizing overload current and reducing inrush current when driving large capacitive loads. The device provides an accurate load current sense that allows for improved load diagnostics, such as open-load detection and overload, enabling better predictive maintenance.
