Trinamic's TMC7300 is the company's second IC for low voltage applications.A power driver with uar-based torque and speed control,You can use 2 (1.8)... 11V dc drive up to two dc motors.
January 6, 2020 Hamburg - TRINAMIC sport control co., LTD. Announces the launch of TMC7300,This is a low voltage driver,A dc motor for peak current up to 2A,Or two dc motors with peak current up to 2.4a.The TMC7300 is powered by single or double lithium ion batteries or at least 2 AA batteries.Ideal for battery-powered devices (such as IoT and handheld devices,Printers, POS applications, toys, cameras and mobile medical devices）.
Because of the integration of the direct bridge,The chip can also be used to control solenoids,Relays and other actuators.Despite its small size - QFN20 packaging,It's only 3x3 millimeters,But the TMC7300 USES integrated power MOSFET and fully integrated DC motor control logic to achieve high power density.Therefore, it can control speed and limit torque, or for torque control operations.
Michael Randt, founder and CEO of the hamburg-based company, explains:By introducing a new series of IC drives for battery-powered applications,We want to inspire innovation.By providing engineers around the world with the tools they need to develop new applications,And turn proven concepts into portable devices for consumers and professionals,Stimulate their imagination.
For ease of use,The TMC7300 comes with a single line UART interface.It can control the direction of up to two dc motors,Velocity and torque.Trinamic development environment (including open source hardware and software),The new chip allows rapid prototyping at lower overhead costs.
Protection and diagnostics support stable and reliable operations,Including PWM control for smooth acceleration and deceleration,Internal current limiter for protection of DC motor and power supply and mechanical load sensing.By using a detecting resistor to achieve the maximum current required,The chip can disable the power amplifier stage and report errors through the interface or DIAG output.
Tmc7300-la with the breakthrough board tmc7300-bob and the evaluation board tmc7300-eval,It will be listed through Trinamic's distribution channel at the end of January 2020.
