PIN ASSIGNMENTS
Pin 1— V
OUT
— 5.0V regulated charge pump.
Pin 2 — CF1P — Positive terminal to the charge
pump flying capacitor, CF1.
Pin 3 — V
— Input pin for the +2.7V to +5.5V
supply voltage.
Pin 4 — C/4 — This is a control line for the
internal charge pump frequency. When this
control line is forced to a logic high, the
internal charge pump frequency is set to
1
/
of
the CLK frequency, provided that Cx8 is
low.
Pin 5 — Cx8 — This is a control line for the
internal charge pump frequency. When this
control line is forced to a logic high, the
internal charge pump frequency is set to x8 of
the CLK frequency.
Pin 6 — CLK — 32.768kHz Clock. Connect
this input pin to an external 32.768kHz clock
PINOUT
to drive the frequency of the charge pump.
Logic low inputs on the C/4 and Cx8 pins sets
the internal charge pump frequency accord-
ing to
Table 1
. Shutdown mode for the
device is set when there is no clock signal
present on this input pin, or when it is pulled
to ground.
Pin 7 — CF2N — Negative terminal to the
charge pump flying capacitor, CF2.
Pin 8 — GND — Ground reference.
Pin 9 — CF2P — Positive terminal to the charge
pump flying capacitor, CF2.
Pin 10 — CF1N — Negative terminal to the
charge pump flying capacitor, CF2.
