The TB6026F is a monolithic, single-channel, high-side switch intelligent power device (IPD) manufactured by Toshiba Semiconductor and Storage. It is designed for use in automotive and industrial applications, offering robust protection and diagnostic features.

Applications

• Automotive high-side switching: Driving lamps, solenoids, and other inductive loads in automotive systems.
• Industrial automation: Controlling actuators, valves, and other loads in industrial equipment.
• Power distribution: Protecting and controlling power distribution circuits.
• Motor control: High-side driver for DC motors.
• Relay replacement: Solid-state replacement for electromechanical relays.

Features

• High-side switch: Controls the high side of the load, providing enhanced safety.
• Overcurrent protection: Protects the device from damage due to excessive current.
• Overtemperature protection: Prevents thermal runaway and ensures reliable operation.
• Short-circuit protection: Safeguards the device and the load from short-circuit conditions.
• Open-load detection: Detects open-load conditions and provides diagnostic feedback.
• Undervoltage lockout: Prevents the device from operating under undervoltage conditions.
• Diagnostic output: Provides feedback on the device's status, such as overcurrent, overtemperature, and open-load conditions.
• Logic-level input: Compatible with standard logic levels for easy interface with microcontrollers and other control circuits.

Benefits

• Enhanced safety: High-side switching and integrated protection features ensure robust and safe operation.
• Improved reliability: Protection features prevent damage to the device and the load.
• Simplified design: Integrated functions reduce the number of external components required.
• Reduced system cost: Integrated functions and smaller package size help to reduce system cost.
• Increased efficiency: Low on-resistance minimizes power dissipation.

Additional Details

The TB6026F typically operates from a supply voltage range of 6V to 36V. The on-resistance is very low which reduces power loss. This IPD is available in a surface mount package such as the HSOP-8. Detailed specifications, including electrical characteristics, thermal performance, and package dimensions, are available in the official Toshiba datasheet.
