Power On Reset (POR) circuitry is included. Upon detection of a low voltage condition, POR is asserted, the
internal registers are reset, and spindle power circuitry is tri-stated. The BEMF is rectified providing power for
actuator retraction followed by dynamic spindle braking. Three Linear regulators and a Shock Sensor circuitry
are also integrated.
The device is built in BCD mixed signal technology allowing dense digital/analog circuitry to be combined with
a high power DMOS output stage.
