VRECT
Outputofthe synchronous rectifiersupplying power to
theretract circuitry.Filteredby an internal 400pF
capacitor. Normally notexternally connected. However,
ifretract commandisto beused, a small signalsilicon
diodemustbeconnectedbetween thispin andVcc
(Cathode toVRECT)tosupply theadditional current
which mayberequired tobraketheVCM.
An external parallel RC network from this point to
ground sets the Brake dELAY:T= 0.45 RC.
Typical values are R = 4M
, C=0.1
μ
F (0.16sec,
delay).
Voltage triplerreservoir capacitor. Thisis used for
the brake operation when power is removed from
the chip. No DC load allowed. 1

prefered.
Positive terminal of charge pump capacitor.
10nF (typ) for Tripler operation;
330nF (typ0 or Doubler operation
Negative terminal of charge pump capacitor.
10nF (typ) for Tripler operation;
330nF (typ)or Doubler operation
Positive terminal of charge pump capacitor for
Tripler operation. 330nF (typ).
Connected tp VHRTRIP for Doubleroperation.
Negative terminal of charge pump capacitor for
Tripler operation. 330nF (typ).
Not connected for Doubler operation.
An external capacitor from this pin to ground sets
the duration of POR after power has been re-
established. T (por) = 32 X C (por)
where: C (por) is in pF and T is expresssed in
μ
s.
Power On Reset. This open drain output goes low
when the voltage at either UV1 or UV2 goes below
1.25V.
Under voltage detector 1. This defines the
VOLTAGE GOOD threshold by comparing the
voltage on this pin to the internal 1.25V reference.
An external resistor divider network and capacitor
filter provides the selection of threshold and supply
noise rejection. There is an internal pull-up (2
μ
A
max). Hysteresis is 20mV.
Spindle Disable Delay . A capacitor connected
between this pin and Vcc programs the delay
between POR and the disabling of the Spindle
section..
Delay = 80 xC (C in pF; Delay in
μ
s)
High tripler/Doubler output. 330nF (typ). 11V max.
Low tripler/Doubler output. 330nF (typ). for stability.
