DATA SHEET PD16873/A/B/C MONOLITHIC 3-ASPECT SPINDLE MOTOR DRIVER MOS Integrated Circuit DESCRIPTION PD16873/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 (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) PD16873 PD16873A PD16873B PD16873C normal normal synchronous synchronous * Built in STANDBY terminal and off the inner circuit at the time of the standby. * Built in START/STOP terminal. Operating short brake works, when ST/SP terminal is off state. * Supply voltage: 5 V drive * Low consumption current: IDD = 3 mA (MAX.) * Thermal shut down circuit (TSD) built in. * Over current protection circuit built in. (Setting by outside resistance) * Low voltage malfunction prevention circuit built in. * Reverse turn prevention circuit built in. * Hall bias switch built in. (synchronized STB signal.) * Loading into 30-pin plastic TSSOP (300 mil).
