LA6585MC
BTL Driver Single‐phase
Full‐wave for Motor Driver
Monolithic Digital IC
Overview
The LA6585MC 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.
Functions and Features
• Pre-driver for Single-phase Full-wave Drive
• Single-phase Full-wave Linear Drive by BTL Output
(Gain Resistance 1 kW−360 kW, 51 dB):
No Switching Noise, which is Optimum for Equipment Requiring
Silence, such as Consumer Equipment Power Supply, Car Audio
System, etc.
• Low-voltage Operation Possible, with Wide Operating Voltage
Range (2.2 to 14.0 V)
• Low Saturation Output (Upper + Lower Saturation Voltage:
V
Osat
(Total) = 1.2 V Typ, I
O
= 250 mA): High Coil Efficiency with
Low Current Drain. Additionally, IC itself Generates only Small Heat
• Built-in Lock Protection and Automatic Reset Circuits
• Built-in FG & RD Outputs
• Built-in Hall bias (V
HB
= 1.5 V)
• Thermal Protection Circuit: When the Large Current Flows due to
Output Short-circuit and the IC Chip Temperature Exceeds 180°C,
this Protective Circuit Suppresses the Drive Current to Prevent Burn
and Damage to IC.
• Extra-small & High Heat Capacity Package
