PIN ASSIGNMENTS
Pin 1— FC — Frequency Control for the
internal oscillator. FC = open,f = 10KHz
OS C
typical; FC = V+, f_OSC = 80KHz typical
Pin 2 — CAP+ — Connect to the positive
terminal of the charge pump capacitor.
Pin 3 — GND — (Voltage Inverter Circuit)
Ground.
Pin 3 — GND — (Positive Voltage Doubler
Circuit) Positive supply voltage input.
Pin 4 — CAP- — Connect to the negative
terminal of the charge pump capacitor.
Pin 5 — OUT — (Voltage Inverter Circuit)
Negative voltage output pin.
Pin 5 — OUT — (Positive Voltage Doubler
Circuit) Ground pin for power supply.
Pin 6 — LV
Low-voltage operation input pin in 660
circuits. In SP6660 circuits can be connected
to GND, OUT or left open as desired with no
effect.
Pin 7 — OSC — Control pin for the oscillator.
Internally connected to 15pf capacitor.
An external capacitor can be added to slow
the oscillator. Be careful to minimize stray
capitance. An external oscillator can be
connected to overdrive the OSC pin.
Pin 8 — V+ — (Voltage Inverter Circuit)
Positive voltage input pin for the power
supply.
Pin 8 — V+ — (Positive Voltage Doubler
Circuit) Positive voltage output.
