Dual high-side switch provides two fully protected 50 mΩ output channels for 24 V industrial loads. The device operates over an 8 V to 36 V specified supply range with 6 V to 58 V extended operation and supports up to 1.2 A continuous output current per channel. Control, configuration, and diagnostics use a 3.3 V and 5 V compatible 16-bit SPI interface at up to 8 MHz, with direct input control also supported. Protection and diagnostics include overcurrent, short-circuit, overtemperature, open-load detection, current sensing, temperature feedback, programmable slew rate, PWM operation, and fail-safe mode. The device is specified for -40 °C to 125 °C ambient operation in a 32-pin SOIC-EP package.
