,, application technology 丨SC2161, application field 丨 Vehicle gauge chip, unique advantages: , 1.
Ratio tracking conversion Type II tracking loop can continuously output position data without conversion delay.
It also suppresses noise and provides tolerance for harmonic distortion in reference and input signals. 2. System fault detection.
Fault detection circuitry can detect signal loss from a resolver, out-of-range input signals, input signal mismatch, or loss of position tracking.
Each fault detection threshold can be individually programmed by the user to be optimized for specific applications. 3. Input signal range.
The sine and cosine inputs support a differential input voltage of 3.
15 Vp−p ± 27%. 4. Programmable excitation frequency.
The excitation frequency can be easily set to multiple standard frequencies in the range of 2 kHz to 20 kHz. 5. Position data in 3 formats.
10-bit to 16-bit absolute angular position data can be accessed via a 16-bit parallel port or a 4-wire serial interface.
The incremental encoder simulation uses a standard A-quad-B format and provides directional output. 6. Digital speed output.
You can access 10-bit to 16-bit signed digital speeds via a 16-bit parallel port or a 4-wire serial interface.
, Application scenarios: DC and AC servo motor control Encoder simulation Electric power steering Electric vehicle Integrated starter generator/alternator Vehicle motion detection and control, Future prospects: ,SC2161 is a resolver-to-digital converter, which cooperates with the resolver to convert the shaft angular position and speed into electrical signals and then convert them into corresponding digital outputs, and then hand them to the main control chip for further processing.
The SC2161 can realize high-precision and high-speed conversion, assist the main control chip to complete real-time detection of the motor state, and use this to dynamically manage the motor and achieve closed-loop control, thereby greatly improving the safety of the motor operation.
