2.3.20 TPS2HC08-Q1

The TPS2HC08-Q1 is a dual-channel, smart high-side switch, with integrated NMOS power FETs and charge pump, designed to meet the requirements of 12V automotive battery systems. The low RON (9.4mΩ) minimizes device power dissipation when driving a wide range of output load current up to 7.5A DC when both channels are enabled or 10A DC when only one channel is enabled. The device integrates protection features such as thermal shutdown, output clamp, and current limit. TPS2HC08-Q1 implements an adjustable current limiting circuit that improves the reliability of the system by reducing inrush current when driving large capacitive loads and minimizing overload current
