BA8206F

Overview

The BA8206F is a tone ringer integrated circuit manufactured by ROHM Semiconductor, designed for generating bell sounds from ringing signals in telecommunication equipment. It operates within a supply voltage range of 14 V to 18 V and supports an operating temperature range of -25°C to +75°C. The device features low current dissipation and can withstand voltages up to 40 V. Key electrical parameters include a typical operating supply current of 1.3 mA and a maximum power dissipation of 450 mW. It is housed in an 8-SOP (SOP-8) surface-mount package with eight terminals.

Feature Summary

• Generates audible bell tones from incoming ringing signals
• Adjustable operation initiation current via external RSL pin
• Supports multiple output load configurations including piezoelectric buzzers and transformer-coupled speakers
• Compatible pin layout with BA8205, BA6565A, and ML8205

Applications

• Telephones
• Multi-function telephones
• Telephone answering machines
• Facsimile equipment

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for end-of-life notifications, as the BA8206F may be discontinued. Ensure packaging integrity matches SOP-8 specifications during receipt inspection.

Selection Notes

Select this IC for telephone systems requiring adjustable tone generation and low standby current. Verify that the external resistance and capacitor values align with desired frequency outputs. Ensure the design accommodates the 14 V to 18 V supply range and thermal constraints of the SOP-8 package.

Part Context

The BA8206F belongs to ROHM's line of communication interface ICs specifically tailored for legacy and modern telephone sets. It serves as a dedicated solution for ring signal processing, replacing discrete transistor-based ringers with a compact, single-chip alternative suitable for space-constrained telecom hardware.

Replacement Considerations

The BA8206F shares pin compatibility with the BA8205, BA6565A, and ML8205. Verify functional equivalence regarding tone frequency control and load driving capabilities before substitution. Check for updated revisions or EOL status from ROHM.
