LA6538T
Overview
The LA6538T is optimal for use as a fan motor driver in equipment, such as notebook personal computers 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.
Functions
BTL output single-phase full-wave linear drive (gain resistance: 180 to 500 k, 360×)
- Since this device generates no switching noise, it is optimal for fan drive in audio equipment, electronic games,
and notebook personal computers.
Supports low-voltage operation and features a wide usable voltage range (VCC = 2.5 to 9.5V).
Low saturation voltage output (Upper side + lower side saturation voltage: VO sat (total) = 0.2V (typ), IO = 100mA)
- 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 2.1V, and the device provides a stable Hall output with excellent temperature
characteristics.
FG output
- The LA6538T provides a speed detection output (an open-collector output).
Built-in thermal protection circuit
- This circuit limits the drive current to prevent damage to or destruction of the IC when the IC chip temperature exceeds
180
°C due to excessive output current caused by load shorting or other problem.
Ultraminiature package (MSOP8: 3.0 × 4.9 × 0.93mm3)
- Allows the circuit board to be miniaturized and a large heat sink to be used.
