PTC used as ring generator ballast.
NOTES:
4. Secondary protection diode bridge recommended is a 2A, 200V type.
5. All grounds (AG, BG, and DG) must be applied before V
CC
or V
BAT
. Failure to do so may result in premature failure of the part. If a user wishes
to run separate grounds off a line card, the AG must be applied first.
6. Application shows Ring Injected Ringing.
