50V – 5A DC Brush Motor Driver – High Performance, High Reliability
This is a powerful yet small-size and low-profile brushed DC motor drive system, with key features like adjustable constant current control, direction control, brake controls, Alert output, PWM for speed control, etc. The BD63150AFM chip is the heart of the project which is one H-bridge motor driver for DC brush motors. This board enables low power consumption by direct PWM or PWM constant current control. Built-in protection circuits in this IC are present. It is possible to output an abnormal detection signal for Wired-OR that notifies each protection circuit operation, and this contributes to the high reliability of this board.
Constant Current Mode or Direct PWM Mode Selection
- Constant Current Mode: By default, this project works in constant current mode. Constant current can be set using Trimmer Potentiometer PR1. Use Input1 and Input2 of CN2 to control Motor Forward, Reverse, and Brake. Please refer to Table 1 for input logic.
- PWM Mode: Replace resistor R1 with 0 Ohms. Adjust the PR1 trimmer potentiometer to 1 to 2V. Use Input1 and Input 2 as external PWM/Logic Input with Maximum Allowable PWM frequency 100Khz. Refer to Table 4 for the input signals diagram.
Features
- Single Power Supply Input Range 8 to 46V DC (rated voltage of 50V)
- Rated Output Current (peak): 5.0A(6.0A)
- Low ON-Resistance DMOS Output
- Forward, Reverse, Brake, Open Function
- Power Save Function
- External PWM Control – PWM Control Mode
- PWM Constant Current Control Adjustable (current limit function)
- Built-in Spike Noise Cancel Function (external noise filter is unnecessary)
- Built-in Logic Input Pull-down Resistor
- Cross-conduction Prevention Circuit
- Output Detection Signal during Abnormal states (Wired-OR)
- Thermal Shutdown Circuit (TSD)
- Over-current Protection Circuit (OCP)
- Under Voltage Lock out Circuit (UVLO)
- Over Voltage Lock out Circuit (OVLO)
- Ghost Supply Prevention (protects against malfunction when power supply is disconnected)
- PCB Dimensions 48.10 x 37.62mm
- Four Mounting Holes 3mm each
