The basic working method of the remote-controlled toy vehicle is to send signals through the radio remote control, which are received and decoded by the receiver within the toy vehicle, thus controlling its operation. Depending on the size of the vehicle, it can be divided into ordinary private trailers, land cruisers, freight containers, rollers, etc. Remote control operations, such as moving forward, back, left or right, are carried out by sending a specific coded signal. These signals are decoded by the decoded circuit inside the receiving chip, which then sends the corresponding control signal to control the vehicle's operation。
Inside the toy car, the electric power is the core component that drives it forward. The toy motor works by wiring the currents onto the fixed wire, generating a rotating magnetic field, which rotates the rotor, thus driving the toycar forward. Specifically, when the current passes through the wire, magnetic lines are generated, creating a magnetic field between the dot and the rotor, which begins to be rotated by magnetic force. When the rotor rotates, the direction of the magnetic line between the ring and the rotor changes, creating a different rotational magnetic field that keeps the rotor moving. This small, light and efficient electric power can provide lasting and stable power to toys。
Sss6226, an industrial net agent, is a 7v-channel straight-stream motor drive that applies to remote-controlled toy vehicles, small-scale electric power, printers, intelligent homes, industrial equipment, etc., in the application of integrated electric power。
The chip supports the range of 2. 4v-7. 2v voltage, allows for the output of peak currents of 2a and incorporates current regulation; allows for two-way control of electric generators, and uses the current decay mode to control the speed of electrical transmissions by wiring. The h bridge is controlled by a two-way logical input, and each arm of the bridge contains a high side and a bottom of the n trench, mosfet, which is subject to conductive electrical resistance of 0. 6 times。
Ss6226 is a direct current power-driven integrated circuit designed for systems operating under low voltage, with a two-channel low-conductive barrier. Four functions are available for the powering/reverse/stop/brakes。
The built-in temperature protection function, when the chip's temperature rises dramatically, the internal circuit shuts off the built-in power switch and cuts load currents。
Characteristics of motor drive chips - ss6226: work voltage range: vdd = 2. 4v to 7. 2v low-altitude current: (typ. 0. 2ua) containing overheat protection low-conductive electrical resistance: 0. 6ohm (sop16)
