12/24V 7A 160W Dual DC motor drive module / board H bridge L298 logic Function characteristics: The tiny size, only 5.5cm * 5.5cm Support 7V ~ 24V voltage, under voltage protection The dual motor interface, each rated output current of 7A It is similar to the L298 control logic, each supporting three linescontrol enable, positive inversion and brake The enable signal can be connected with the PWM, positive inversion control signal can be connected in series to limit switch The control signal by current drive mode, the vast majority supportsingle chip direct drive We use optocoupler isolation for all control signal The electrostatic discharge circuit Technical Parameters: Input voltage range : DC 6.5V ~ 27V Rated input voltage : DC 12V / 24V Output channels: 2 channels Rated output current per channel : 7A Peak output current per channel : 50A Rated output power per channel : 84W (12V power supply) 168W (24V power supply) Control signal voltage : 3 ~ 6.5V Each control signal current : 3 ~ 11mA The minimum effective PWM pulse width : 5us Working temperature : -25 °C ~ 80 °C Dimensions : 5.5cm x 5.5cm x 2.0cm Summary of principles“ The H bridge module using gate circuit, pipe combination and MOS to achieve motor reversing, braking and speed control. Both output current is large and similar control signal L298 flexible logic. Interference treatment methods: control signals optocoupler isolation, power peak voltage suppression. Control signal logic: the realization of control logic similar to the L298 using the gate circuit. The method of realizing H bridge: the use of P and N complementary MOS tube H bridge. Power supply undervoltage protection: the realization ofundervoltage protection using reset chip. Payment Policy: We ONLY accepted PayPal payment.
