Description

The UPD168803FC-AN2-E1 is a CD-ROM/DVD-ROM 3-phase spindle motor driver. It consists of a CMOS controller and MOS bridge outputs. The drive method used is 3-phase full-wave PWM with MOSFETs at the output stage, resulting in reduced power consumption compared to drivers that use bipolar transistors. The UPD168803FC-AN2-E1 is designed in a 30-pin shrink SOP package, making it more compact in size.

Specifications and 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
