Product Summary
The TCM1520AP is a monolithic ring-detection integrated circuit designed for use in isolated or nonisolated telephone applications. The device uses a modified form of the Texas Instruments BIDFET technology to combine low-voltage CMOS and high-voltage bipolar input/output circuitry. The TCM1520AP features efficient high-voltage (40 V to 150 V) operation with a typical current drain of 1 mA.The TCM1520AP incorporates lightning and transient protection that is designed to withstand lightning strikes of 1.5-kV amplitude and 200-ms duration and also features built-in circuitry to avoid tapping or false triggering due to transients.
