F6406/G
2-PHASE DC-FAN MOTOR
PRE-DRIVER IC
DESCRIPTION
LINEAR INTEGRATED CIRCUIT
The UTC
F6406/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
F6406
is with RD option and
UTC
F6406G
with FG.
FEATURES
SOP-8
* 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 (F6406)
* FG(frequency generator) output (F6406G)
