NOTE

Initial supply voltage (VSI) is the supply voltage required to start the tone ringer oscillation.

Sustaining voltage (VSUS) in the supply voltage required to maintain oscillation.

VTR and ITR are the conditions applied to trigger to start for VSUS¡ Â

VCC¡ ÂVSI

VDIS and IDIS are the conditions applied to trigger to inhibit oscillation for VSI¡ ÂVCC

Trigger current must be limited to this value externally.
