L7590CAE

The L7590CAE is one member of the L7590C family which is designed as the telephone ringing driver that produces a low-frequency sinusoidal ringing signal for analog telephone loops. This device is optimized for low power dissipation and is available in a 16-pin, surface-mount package. Features of the L7590CAE are:(1)requires 5 V, a high-value negative dc supply, and a digital input sequence;(2)low power dissipation in idle and ringing modes;(3)built-in current limiting;(4)ringing capability:40 Vrms into 5 North American REN and 30 mApeak into 4 German REN;(5)applies a battery-backed, single-ended, sinusoidal ringing signal to the telephone loop.

The absolute maximum ratings of the L7590CAE can be summarized as:(1)VDD:7.0 V;(2)VNEG:-200 V;(3)timing input voltage:-0.5 to 7.0 V;(4)storage temperature range:-40 to 125 °C;(5)maximum junction temperature:150 °C;(6)relative humidity range:5 to 95 %.
