µPD16873/A/B/C
MONOLITHIC 3-ASPECT SPINDLE MOTOR DRIVER
MOS Integrated Circuit
DESCRIPTION
µPD16873/A/B/C is 3 aspect spindle motor driver that composed by CMOS control circuit and MOS bridge output.
The consumption electric power can be substantially reduced to the screwdriver which used a conventional Bipolar
transistor by the adoption of 3 aspect all-wave PWM methods and making an output paragraph MOSFET.
FEATURES
• Low On resistance.
(The summation of the on resistance of the upper and lower MOSFET) RON = 0.
6 Ω (TYP.
) • Low consumption power for 3 aspects all-wave PWM drive method.
• Index pulse (FG pulse) output function built in.
• By the PWM-drive form and the IND pulse...
