uPD16836 Description
The µPD16836 is a three-phase spindle motor driver for CD-ROM drives which consists of a CMOS control circuit and MOS bridge output. It employs a three-phase full-wave PWM driving method and a MOS FET in the output stage to lower the power consumption pared with drivers using conventional bipolar transistors.
uPD16836 Key Features
- Low ON resistance (Sum of ON resistance of top and bottom transistors) Ron = 1.2 Ω (TYP.)
