PD16873/A/B/C

MONOLITHIC 3-ASPECT SPINDLE MOTOR DRIVER

DESCRIPTION

PD16873/A/B/C is 3 aspect spindle motor driver that composed by CMOS control circuit and MOS bridge output.

µ

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)

µ

PD16873 normal 3 phase composition output (18 pul ses/turn)

µ

PD16873A normal 1 phase output (6 pulses/turn)

µ

PD16873B synchronous 1 phase output (6 pulses/turn)

µ

PD16873C synchronous 3 phase composition output (18 pulses/turn)

• 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).
