DESCRIPTION
The µPD16882 is a CD-ROM/DVD-ROM 3-phase spindle motor driver consisting of a CMOS controller and MOS bridge outputs.
By employing 3-phase full-wave PWM as the drive method and MOSFETs at the output stage, it has been possible to reduce the power consumption of the µPD16882 ever further than the drivers that use bipolar transistors.
By using a 30-pin shrink SOP package, a more compact-size has been achieved.

FEATURES
• Supply voltage for controller block: 5 V, supply voltage for output block: 12 V
• Low on-state resistance (total on-state resistance of upper and lower transistors) output RON = 1.1 Ω (TYP.)
• Low power consumption due to 3-phase full-wave PWM drive method
• On-chip hole bias switch (linked with STB pin)
• On-chip IND pulse switching function
• START/STOP pin included, acting as a brake during STOP
• Brake pin enabling reverse brake and short brake switching
• Standby pin included, turning off internal circuit in standby (Output high impedance)
• Low current consumption: IDD = 3 mA (Max.), IDD (ST) = 1 µA (Max.)
• On-chip thermal shutdown circuit
• On-chip undervoltage lockout circuit
• Overcurrent protector (can be externally set by external resistor)
• On-chip reverse revolution prevention circuit
• 30-pin plastic shrink SOP (7.62 mm (300))
