L9110S Dual H-Bridge Motor Driver

The L9110S Dual H-Bridge Motor Driver is a board I/O module in the LabWired part catalog. Its catalog type is l9110s. It connects to the MCU over GPIO. The catalog gives a supply range of 2.5–12 V. It has 10 pins. This part is its pins. There is no separate device model because the MCU’s own GPIO/PWM/ADC model already is the simulation.

From the catalog: L9110S (HG7881) dual H-bridge. A dc-motor on MOTOR-A/MOTOR-B runs its plant twin through A-IA/A-IB or B-IA/B-IB (PWM on an IN pin); the driver itself is its pins.

How to simulate the L9110S Dual H-Bridge Motor Driver in LabWired

  1. Open the Playground at app.labwired.com and place an MCU board.
  2. Add the L9110S Dual H-Bridge Motor Driver (catalog type l9110s).
  3. Connect VCC and GND to the supply and ground of the board. Use a supply inside the catalog range of 2.5–12 V.
  4. Connect A-IA, A-IB, B-IA and B-IB to pins that can output PWM.
  5. Connect MOTOR-A1, MOTOR-A2, MOTOR-B1 and MOTOR-B2 as your circuit needs.
  6. Run the firmware. It reads and drives these pins through the GPIO, PWM and ADC models of the MCU. The part has no separate device model.
