LINEAR INTEGRATED CIRCUIT
2-PHASE DC-FAN MOTOR
PRE-DRIVER IC
DESCRIPTION
The UTC SK6406/G is a 2-phase pre-driver IC for dc-fan
motors, providing the functions of motor lock protection, auto-restart,
and rotation detection signal output. UTC SK6406 is with RD option
and UTC SK6406G with FG.
FEATURES
* Wide supply voltage range of 2.5V to 30V
* Lock protection
* Auto-restart when the motor lock is undone
* RD(latch-type lockup detection) output (SK6406)
* FG(frequency generator) output (SK6406G)
Lead-free:
SK6406L/SK6406P
Halogen-free: SK6406GL/SK6406GP
