Overview
The BD62120AEFJ-E2 is a single-channel H-bridge motor driver IC designed for DC brushed motors, manufactured by Rohm Semiconductor. It utilizes DMOS technology and operates within a supply voltage range of 8V to 28V, with a maximum rated voltage of 36V. The device supports an output current of 2A continuous and 3A peak, featuring a typical on-resistance of 0.65Ω. It accepts ON/OFF logic interfaces and external PWM control. The component is housed in an 8-HTSOP-J package with dimensions of 4.9x6.0mm and functions across a temperature range of -25°C to 85°C.
Feature Summary
- Supports direct PWM driving for high-efficiency operation
- Integrates comprehensive protection circuits including thermal shutdown, over-current protection, and cross-conduction prevention
- Features built-in logic input pull-down resistors and ghost supply prevention mechanisms
Applications
- Printers (Multi-function, Laser, Inkjet, Photo, FAX, Mini)
- Small appliances such as vacuum cleaners
- Factory automation equipment
- Robotics systems
- Point of Sales (POS) machines
Procurement Notes
Verify the specific suffix E2 against the datasheet to confirm pinout and electrical characteristics match the design requirements. Ensure the HTSOP-J8 package footprint aligns with the PCB layout. Confirm that the application does not involve automotive use, as this standard-grade product is explicitly excluded from automotive applications. Check RoHS compliance status if required by local regulations.
Selection Notes
Select this component for DC brushed motor control applications requiring up to 2A continuous current. It is suitable for designs needing integrated protection features to enhance reliability without external components. Consider the 8-pin surface mount package for space-constrained layouts. Evaluate thermal management needs given the 0.65Ω on-resistance at higher load currents.
Part Context
This part belongs to the BD62120 series of motor drivers from Rohm Semiconductor. It is specifically engineered for low-power consumption through direct PWM control. The series includes variants like the BD62120FP for different voltage ranges. The BD62120AEFJ-E2 represents a standard-grade option suitable for general-purpose industrial and consumer electronics rather than specialized automotive environments.
Replacement Considerations
The BD62120FP is a related variant within the same family but operates at lower voltages (3-5.5V). Verify voltage compatibility before substitution. No other direct public substitute part numbers are confirmed in the provided documentation.
