TSB582

TSB582 is a high-performance dual-channel, low-side driver IC manufactured by STMicroelectronics, designed for precise control of inductive loads such as solenoids, relays, and motors. It features two independent output stages capable of driving loads up to 30 V with a maximum continuous current of 1.5 A per channel, making it suitable for demanding automotive and industrial applications. The device operates from a supply voltage range of 4.5 V to 30 V, ensuring compatibility with a wide variety of power systems. Each channel includes an integrated N-channel MOSFET with low on-resistance (typically 75 mΩ), enabling efficient switching and minimal power dissipation. The TSB582 incorporates comprehensive protection mechanisms including overcurrent protection, thermal shutdown, and under-voltage lockout, which enhance system reliability and prevent damage during fault conditions. Additionally, the internal clamp diode provides flyback energy management for inductive load suppression, eliminating the need for external components in many designs. The IC supports both logic-level and PWM inputs, allowing flexible integration into microcontroller-based control systems. Its input threshold levels are compatible with standard CMOS and TTL logic families, simplifying interface design. Each channel also includes a diagnostic output that indicates open-load or short-circuit conditions, enabling real-time monitoring and fault detection without requiring additional external sensors. Designed for robust operation in harsh environments, the TSB582 meets AEC-Q100 qualification standards for automotive applications, including extended temperature range (-40°C to +150°C junction temperature). It is packaged in a compact, thermally optimized PowerSSO-20 surface-mount package, facilitating high-density PCB layouts while ensuring effective heat dissipation. This device is widely used in automotive systems such as fuel injectors, door locks, and HVAC controls, as well as in industrial automation equipment like valve actuators and motor drives. Its combination of high drive capability, built-in diagnostics, and rugged design makes it ideal for safety-critical and high-reliability applications where consistent performance and fault tolerance are essential.
