UC3173A
VL: Logic portions of the UC3173A are powered by this
supply pin, including the reference, UVLO, the UV com-
parators, and the PRKDRV and PWROK outputs. This
pin is a low current supply that would normally be tied to
the VC pin, or to a parking hold up capacitor for ex-
tended parking operation with very low recovered back
emf.
VPARK: The auxiliary inverting input to the A amplifier,
activated during park conditions on the UC3173A. An in-
ternal auxiliary non-inverting input is connected to the
1.3V reference. When the auxiliary inputs are activated,
the A amplifier will force a programmed voltage at its out-
put for a maximum back-emf/velocity retract of the head.
The park condition on the UC3173A is always activated
by any one of the following four conditions, 1: a low con-
dition on either of the UV inputs, 2: a high input level at
the Park input, 3: a UVLO condition at the VL supply pin,
and 4: activation of the TSD, (thermal shutdown) protec-
tion circuit. During a UVLO condition at the VL pin the
auxiliary inputs to the A amplifier are over-ridden, and
the A amplifier output is forced to its high state.
UV1&2: Inputs to the UV comparator, these inputs are
high impedance sensing points used to monitor external
supply conditions. Either of the inputs going low will force
the device into a park condition, and force the PWROK
output to an active low state. If either of these inputs is
not used it should be connected to a voltage greater
than 1.3V.
