Overview
DATA SHEET 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 pattern, 4 kind, line-up PWM method Pattern of IND pulse (at 12 pole motor) 3 phase composition output (18 pulses/turn) 1 phase output (6 pulses/turn) 1 phase output (6 pulses/turn) 3 phase composition output (18 pulses/turn) µPD16873 µPD16873A µPD16873B µPD16873C normal normal synchronous synchr...
