Présentation

Equivalent

The SMI810 is a USB-to-SATA bridge controller. Equivalent products include:
- JMicron JMS578
- ASMedia ASM1153E
- Realtek RTL9210 (supports NVMe)
- Initio INIC-3637
These chips offer similar USB 3.0 to SATA bridging functionality, with varying features like UASP support or NVMe compatibility. Choose based on specific needs like speed or drive compatibility.

Features

The SMI810 is a high-performance 3D Hall-effect sensor designed for precise angular and linear position sensing. Key features include:
- Contactless Sensing: Measures magnetic fields without physical contact, enhancing durability.
- High Accuracy: Delivers precise angle measurement (typically ±0.5° error).
- Wide Operating Range: Supports 360° rotation detection and linear displacement.
- Digital Output: Provides I²C, SPI, or PWM interfaces for easy integration.
- Low Power Consumption: Suitable for battery-operated applications.
- Robust Design: Operates in harsh environments (-40°C to +150°C).
- Programmable Settings: Allows customization for sensitivity, output format, and more.
Ideal for automotive (steering, pedals), industrial (motor control), and consumer (knobs, joysticks) applications.

Pinout

The SMI810 is a Hall-effect sensor IC designed for rotary position sensing. It typically comes in a 4-pin package (e.g., SIP-4 or TO-94UA).
Pin Functions:
1. VCC – Power supply (typically 3.5V to 24V).
2. GND – Ground connection.
3. Output – Digital open-drain output (pulls low when a magnetic field is detected).
4. Enable – Optional control pin to activate/deactivate the sensor (if available; some variants may omit this).
The SMI810 detects changes in magnetic fields, commonly used in speed or position sensing (e.g., in automotive or industrial applications). Its output switches based on the presence of a south or north pole magnet.
*Note: Exact pinout may vary slightly by manufacturer—always check the datasheet for your specific model.*
