User’s Guide DC Brushed Motor Driver 36V 1 Channel (1A/2A/3A) DC Brushed Motor Driver BD621x0AEFJ Evaluation Board Introduction This user’s guide will provide the necessary steps to operate the Evaluation Board of ROHM’s BD621x0AEFJ DC Brushed Motor Driver. This document includes the external parts, operating procedures and application data. Description This Evaluation Board was developed for ROHM’s family of DC Brushed Motor Driver: BD62130AEFJ (3A), BD62120AEFJ (2A) and BD62110AEFJ (1A). BD621x0AEFJ are built-in 1 channel H bridge motor drivers for DC brushed motors. This family of driver can drive high efficiency by a PWM signal directly to input pins. There are built in protection circuits in this IC. Each protection circuit operation contributes to set high reliability. Application Small appliances (Vacuum cleaners), Factory Automation, Robotics, Point of Sales (POS) machines, Gaming Machines, Scanners, Printers (Multi-function Printer, Laser Printer, Inkjet Printer, Photo Printer, FAX, Mini Printer), Plain Paper Copier (PPC), and any application that requires motor drivers for DC Brushed Motor.

Evaluation board setup – test points, connectors, and switches S1 and S2 Evaluation board setup – Switches S1 and S2 are used to connect IN1 and IN2 pin to either 5V (“H”) or as open (“L). When connected as open (“L”) and internal pulldown resistor will pull IN1 and IN2 to ground if nothing is connected to IN1 and IN2 test points. Figure 6. © 2022 ROHM Co., Ltd.

Connect a DC brushed motor to connector CN1 (or to OUT1 and OUT2 test points) using wires. 2. Connect power supply between VCC and GND test points. 3. Connect a separate 5V to 5V test point. 4. Operate the switches “S1” and “S2” based on Input and Output operation shown in Table 2. Operating procedure: Using external PWM signal to control IN1 and IN2 1. Connect a DC brushed motor to connector CN1 (or to OUT1 and OUT2 test points) using wires. 2. Connect power supply between VCC and GND test points. 3. Ensure that the switches S1 and S2 are pointed towards the “L” position (right side) so that IN1 and IN2 are not connected to 5V. See Figure 5 for description. 4. Connect an external microcontroller to IN1 and IN2 test points. 5. Operate the DC brushed motor based on Table 3 suggestion. Pin configuration Figure 7. Pin configuration Table 4.
