ISO8200B

ISO8200B Description

The ISO8200B from STMicroelectronics is a high-performance 8-channel power driver designed for high-side switching applications, offering robust 10.5V to 36V load voltage support with a maximum output current of 700mA per channel. This surface-mount device integrates galvanic isolation, ensuring reliable operation in noisy environments while maintaining 1:1 input-to-output ratio for precise control. Packaged in a PWRSO36 tube, it complies with ROHS3 and REACH environmental standards, making it suitable for modern, eco-conscious designs. Its parallel interface simplifies integration, while 120mOhm typical Rds(on) minimizes power losses, enhancing efficiency.

ISO8200B Features

• High-Side Configuration: Optimized for driving relays, solenoids, and other inductive loads.
• Advanced Protection: Built-in current limiting (fixed) and over-temperature fault protection with auto-restart functionality for fail-safe operation.
• Diagnostic Capability: Status flag provides real-time fault monitoring, improving system reliability.
• Galvanic Isolation: Ensures signal integrity in high-noise industrial environments.
• Low Power Dissipation: 120mOhm Rds(on) reduces heat generation, enabling compact designs.
• Wide Operating Range: Supports 10.5V–36V loads, ideal for 12V/24V automotive and industrial systems.

ISO8200B Applications

• Industrial Automation: Drives PLCs, motor controllers, and solenoid valves with isolated control.
• Automotive Systems: Powers relays and actuators in body control modules (BCMs) and lighting systems.
• Power Distribution: Manages multi-channel loads in telecom/base station power supplies.
• Home Appliances: Controls high-current circuits in smart appliances with safety diagnostics.

Conclusion of ISO8200B

The ISO8200B stands out as a highly integrated, robust power driver for demanding applications. Its combination of galvanic isolation, low Rds(on), and diagnostic features makes it superior to conventional drivers, particularly in industrial and automotive systems where reliability is critical. With 8-channel output, fault resilience, and wide voltage compatibility, it simplifies design while meeting stringent ROHS3/REACH standards. Engineers seeking a compact, efficient, and fault-tolerant solution for high-side switching will find the ISO8200B an optimal choice.
