Description
The UPD168807 is a 3-phase spindle motor driver designed for CD-ROM/DVD-ROM applications. It features a CMOS controller and MOS bridge outputs. With its 3-phase full-wave PWM drive method and MOSFETs, the UPD168807 offers reduced power consumption compared to drivers that use bipolar transistors. It is also packaged in a compact 30-pin shrink SOP package.
Specifications and features
- Supply voltage for controller block: 5 V
- Supply voltage for output block: 12 V
- Total on-state resistance of upper and lower transistors: 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 acts as a brake during STOP
- Brake pin enables reverse brake and short brake switching
- Standby pin turns 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 (externally settable by external resistor)
- On-chip reverse revolution prevention circuit
- 30-pin plastic shrink SOP (7.62 mm (300))
