ISO8200BQ

ISO8200BQ Description

The ISO8200BQ from STMicroelectronics is a high-performance 8-channel power driver designed for high-side switching applications. This surface-mount IC, packaged in a 32-TFQFPN format, operates within a 10.5V to 36V load voltage range, making it suitable for industrial and automotive systems requiring robust power distribution. With a maximum output current of 700mA per channel and a low Rds(on) of 120mΩ (typical), it ensures efficient power delivery with minimal losses. The device supports a 1:1 input-to-output ratio and features a parallel interface for simplified control. Its REACH and RoHS3 compliance underscores its adherence to environmental and safety standards.

ISO8200BQ Features

• High-Side Configuration: Ideal for driving relays, solenoids, and other inductive loads.
• Advanced Protection: Integrates current limiting (fixed), over-temperature, over-voltage, and UVLO safeguards for enhanced reliability.
• Auto-Restart & Status Flag: Automatically recovers from faults and provides diagnostic feedback, reducing downtime.
• Low Power Dissipation: Optimized Rds(on) minimizes heat generation, improving thermal performance.
• Industrial Robustness: MSL 3 (168 hours) rated, ensuring durability in harsh environments.
• Parallel Control Interface: Simplifies integration with microcontrollers and logic circuits.
