BD2270HFV-LBTR

Gate Driver Overview

The BD2270HFV-LBTR is a high-side N-channel MOSFET driver IC designed for industrial applications. It integrates a charge pump circuit to drive external N-ch MOSFETs and includes an output discharge FET. The device features a soft start circuit and an analog control input with hysteresis for power sequence management. Operating on a supply voltage of 2.7V to 5.5V, it consumes typically 50µA. The turn-on time is 130µs, and it operates within a temperature range of -25°C to 85°C in a 1.6x1.6mm HVSOF5 package.

Gate Driver Feature Summary

• Integrates a charge pump circuit to enable driving of external N-channel power MOSFETs without additional bootstrap components.
• Includes an internal output discharge FET for rapid de-energization of the load.
• Features a built-in comparator with hysteresis at the control input terminal for stable power-on timing control.
• Incorporates a soft start circuit to manage inrush current during startup.

Gate Driver Applications

• Industrial equipment power switching
• High-side switch configurations for N-channel MOSFETs
• Power sequence control systems

Gate Driver Procurement Notes

Verify the specific suffix LBTR against the manufacturer's official ordering information to ensure correct packaging and tape specifications. Confirm that the HVSOF5 package dimensions align with the target PCB layout requirements. Check for any recent design lifecycle notices or obsolescence warnings directly from Rohm Semiconductor documentation before finalizing procurement plans.

Gate Driver Selection Notes

Select this component when a dedicated high-side driver for external N-channel MOSFETs is required in space-constrained industrial designs. The integrated charge pump eliminates the need for external bootstrap capacitors, simplifying the bill of materials. Ensure the application voltage does not exceed the 5.5V maximum limit and that the analog control interface matches the system's signal levels.

Gate Driver Part Context

This part belongs to the BD2270 series of high-side switch controllers by Rohm Semiconductor. It is specifically engineered for long-term supply stability in industrial markets. The device complements other power management solutions by providing precise control over external power stages rather than integrating the power switch itself.
