ST's TSB582 dual high-output amplifier simplifies driving circuits for inductive and low-resistive loads such as industrial motors, valves, resolvers, and automotive electric steering systems, and automatic parking.the TSB582 uses a 4V-36V power supply and consists of two operational amplifiers (op amps), each with a sink/source current of up to 200mA, which can bridge direct loads, allowing one TSB582 to replace two single-channel power op amps or High-current drivers built from discrete components. By integrating two op amps in the same package, the TSB582 can save up to 50% board space and reduce bill of materials costs.
TSB582 is available in two versions: industrial grade and automotive grade. The industrial version is suitable for controlling robot motion and position, conveyor belts and servo motors. Automotive applications include motor rotor position detection such as electric steering and electric drive motors, as well as autonomous driving assistance systems and autonomous vehicles. wheel rotation tracking. It also features internal short-circuit and thermal protection, rail-to-rail output, and gain bandwidth (GBW) up to 3.1MHz. Both industrial-grade and automotive-grade versions have a temperature range of -40°C to 125°C, enhanced EMI immunity, and ESD immunity up to 4kV HBM.
The new products are available in two low thermal resistance packages: SO8 with exposed thermal pad and DFN8 3mm x 3mm package with exposed thermal pad and wettable sides. The wettable side tin plating process is convenient for checking whether the product meets the automotive quality assurance requirements after welding. DFN8 3mm x 3mm packaged industrial-grade products are already on the market, and DFN8 automotive-grade products and SO8 industrial-grade and automotive-grade products will be released in the third quarter of 2022.
