LA6538T Description
ENN6518 Monolithic Linear IC LA6538T Single-Phase Full-Wave Fan Motor Driver Overview The LA6538T is optimal for use as a fan motor driver in equipment, such as notebook personal puters and electronic game units, that requires miniaturization and low noise levels. This device achieves highly efficient single-phase bipolar fan motor drive by providing a low saturation voltage BTL output. Ultraminiature package...
LA6538T Key Features
- BTL output single-phase full-wave linear drive (gain resistance: 180 to 500 kΩ, 360×)
- Since this device generates no switching noise, it is optimal for fan drive in audio equipment, electronic games, and no
- Supports low-voltage operation and features a wide usable voltage range (VCC = 2.5 to 9.5 V)
- Low saturation voltage output (Upper side + lower side saturation voltage: VOsat(total) = 0.2 V (typ), IO = 100 mA)
- This device achieves a high coil efficiency for low current drain, and generates minimal heat in the IC itself
- Constant-voltage Hall bias output
- The Hall element is regulated at 2.1 V, and the device provides a stable Hall output with excellent temperature characte
- FG output
- The LA6538T provides a speed detection output (an open-collector output)
- Built-in thermal protection circuit
