LA6585M
Overview
Functions and features
Ordering number : EN8776
The LA6585M is single-phase bipolar fan motor is driven, through BTL output linear drive, at high efficiency, low
power, and low sound by suppressing the reactive power. Lock protection, rotary signal circuits are incorporated, which
is optimum for the notebook PC, consumer equipment power supply, car audio system, CPU cooler, etc. that require
high reliability and low noise.
• Pre-driver for single-phase full-wave drive
• Single-phase full-wave linear drive by BTL output (gain resistance 1kΩ-360kΩ, 51dB)
• Low-voltage operation possible, with wide operating voltage range (2.2 to 14.0V)
• Low saturation output (Upper + lower saturation voltage : V O sat (total) = 1.2Vtyp, I O = 250mA)
• Built-in lock protection and automatic reset circuits
• Built-in FG & RD outputs
• Built-in Hall bias (V HB = 1.5V)
• Thermal protection circuit
• Extra-small & high heat capacity package
: No switching noise, which is optimum for equipment requiring silence, such as consumer equipment power supply,
: High coil efficiency with low current drain. Additionally, IC itself generates only small heat.
: When the large current flows due to output short-circuit and the IC chip temperature exceeds 180°C, this protective
car audio system, etc.
circuit suppresses the drive current to prevent burn and damage to IC.
