Power Management Features
Low Power Interrupt:
The low power interrupt operation occurs when the power supply voltage (5V,12V) level drops below each threshold voltage.
The threshold voltage (Vth) and time delay (Tdly) may be adjustable by the external component value.
Figure 12. Power on reset block schematic
Power On Reset
The power-on reset circuit monitors the voltage level of both +5V or +12V power supplies and chip temperature (thermal shut
down). The power-on reset circuit disables the spindle, and the whole VCM circuit when the power supply voltage level drops
below the reference voltage.
