The TS31002 is a telephone bell replacement with low current drain, adjustable 2-frequency tone, adjustable warbling rate, extension tone ringer modules, alarms or other alerting devices
The TSC TS31002 is a bipolar integrated circuit designed for telephone bell replacement. It features low current drain, adjustable 2-frequency tone, and adjustable warbling rate. The device includes built-in hysteresis to prevent false triggering and rotary dial 'Chirps'.
The document provides absolute maximum ratings, recommended operating conditions, and detailed electrical characteristics including initiation supply voltage, sustaining voltage, and output voltage levels. It also includes application circuits and notes on how to use the RSL pin to program supply current characteristics.
| Operating Voltage | 13 to 36V |
|---|---|
| Ringing Start Voltage | 36V (max.) |
| Initiation Supply Voltage | 16.8 = 21.2 V |
| Sustaining Voltage | 9.5 = 12.2 V |
| High Frequency 1 | 461 = 563 Hz |
| Low Frequency | 9.0 = 11.0 Hz |
It is a bipolar integrated circuit designed for telephone bell replacement.
The supply initiation current can be changed by grounding the RSL Pin (Pin 2) through a resistor Rs.
