BD62120JEFJ-E2

Overview

The BD62120JEFJ-E2 is a single-channel H-bridge motor driver designed for DC brushed motors. It supports a power supply voltage range of 8 V to 28 V with a maximum rating of 36 V. The device delivers a rated output current of 2 A and a peak current of 3 A, featuring an on-resistance of 0.65 Ω typical. Operating within a temperature range of -25°C to +85°C, it utilizes DMOS technology in an HTSOP-J8 package.

Feature Summary

• Direct PWM control capability for high-efficiency operation
• Integrated protection circuits including thermal shutdown, over-current protection, and cross-conduction prevention
• Built-in logic input pull-down resistors and ghost supply prevention mechanisms

Applications

• Small appliances such as vacuum cleaners
• Factory automation systems
• Robotics applications
• Point of Sales (POS) machines
• Printers including multifunction, laser, inkjet, and photo printers

Procurement Notes

Verify the specific suffix E2 against the manufacturer's latest datasheet to confirm RoHS compliance and pinout configuration. Ensure the application circuit accommodates the 36 V absolute maximum rating and that thermal management aligns with the 3.75 W power dissipation limit in the HTSOP-J8 package. Confirm compatibility with the required operating temperature range.

Selection Notes

Select this component for designs requiring a single-channel driver with robust protection features and direct PWM interface. It is suitable for applications needing up to 2 A continuous current without external heat sinks if thermal constraints are met. Consider the 8 V minimum supply voltage when designing power rails.

Part Context

This part belongs to ROHM’s series of DC brushed motor drivers. It is functionally similar to the BD62120AEFJ-E2 but distinguished by its specific packaging and suffix designation. The device integrates both logic and power stages into a compact surface-mount solution.

Replacement Considerations

The BA6219BFP-YE2 is listed as a recommended replacement by the manufacturer, though it utilizes bipolar technology and a different HSOP25 package. Verify electrical parameter compatibility before substitution.
