Description
µPD16873/A/B/C is 3 aspect spindle motor driver that composed by CMOS control circuit and MOS bridge output.
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 o.
