LV8163QA
Bi-CMOS IC
Fan Motor Driver
Single-Phase Full-Wave Driver
http://onsemi.com
Overview
The LV8163QA is a driver IC for single phase fan motor which operates noiselessly by BTL linear output method.
The LV8163QA has variable speed function that corresponds to external PWM single input. Therefore, this IC is
suitable for CPU cooler for note PC and the like which requires low power consumption, noiseless operation and
variable speed functions.
Functions
• Single phase full wave drive by BTL output method.
• Speed control function by PWM input.
• Integrated lock protector and auto recovery circuit.
• Standby mode and quick start function.
• Hall bias output pin.
• Startup support function (100% DUTYSTART)
• FG signal pin, RD signal pin
• Integrated TSD (Thermal ShutDown) circuit

Caution 1) Absolute maximum ratings represent the value which cannot be exceeded for any length of time.
Caution 2) Even when the device is used within the range of absolute maximum ratings, as a result of continuous usage under high temperature, high current,
high voltage, or drastic temperature change, the reliability of the IC may be degraded. Please contact us for the further details.
Stresses exceeding Maximum Ratings may damage the device. Maximum Ratings are stress ratings only. Functional operation above the Recommended Operating
Conditions is not implied. Extended exposure to stresses above the Recommended Operating Conditions may affect device reliability.

LV8163QA
*4 < PWM pin >
Motor speed control sifnal input pin.
PWM pin is pulled up at 500kΩ in LV8136QA.
Resistance of 500kΩ is used for full-speed setting when PWM pin is open.
In order to control motor speed using open Collector input method (open drain), pull-up is required using suitable
resistance.
Pull-up resistance is not required when motor speed is controlled by Push-pull input method.
The order of power supply is optinal; either to power supply voltage or PWM input, under one of the following
conditions.
1) When open collector input method is used.
2) Pull-up resistance is not implemented and Push-pull input method is used.
It is recommended to connect a resistance greator than 1kΩ in series to protect PWM pin against open GND and
misconnection.
*5 < FG pin >
Used as rotation counter.
This pin is open drain output. You can count rotations according to phase change.
This pin is set to off during standby mode.
Make sure to set this pin open when unused.
It is recommended to connect a resistance greater than 1kΩ in series to protect PWM pin against open GND and
misconnection.
*6 < RD pin >
Used as lock detector.
This pin is open drain output. During rotation, RD pin is set to low-level voltage. During lock detection, it is set to off.
During standby, it is set to low-level voltage.
Make sure to set this pin open when unused.
It is recommended to connect a resistance greator than 1kΩ in series to protect PWM pin against open GND and
misconnection.
*7 < Low power dissipation during standby >
During standby, the fan motor used in LV8136QA can reduce power dissipation into 10µA (under room temperature,
Typ).
However, power dissipation cannot be reduced into 10µA under the following conditions.
• When bias of Hall element is supplied from power supply:
→ Current flowing into Hall element increases.
• When pull-up resistor is used to PWM pin
→ During standby, the current flowing into pull-up resistor increases because PWM pin must be set to low-level
voltage.
• When using RD pin
→ During standby, the current flowing into pull-up resistor increases because RD pin turns low-level voltage.
