Introduction
The SL477-4 is a low-power, low-cost single-coil DC brushless motor full-bridge driver, specifically designed for small fan motor applications. Its internal circuitry integrates a Hall sensor, temperature compensation, chopper offset cancellation, voltage regulator, over-temperature protection, and a low on-resistance full-bridge driver. The device features reverse polarity protection, eliminating the need for external diodes. Available in a TO-94 package, with an operating temperature range of -40~130℃.
Features
- Wide operating voltage range: 3.5~28V
- Low quiescent current: 1.5mA
- Maximum output current: 350mA
- Output logic: When N-pole approaches the front side, DOB goes HIGH to LOW and DO goes LOW to HIGH; when S-pole approaches the front side, DOB goes LOW to HIGH and DO goes HIGH to LOW
- Built-in over-temperature protection circuit
- Reverse polarity protection, no external diode required
- Integrated low on-resistance full-bridge driver
- ESD (HBM) rating: 4000V
- Suitable for DC brushless motors and fan circuits
