L7590C Telephone Ringing Driver
Features
s
Description
The L7590C Telephone Ringing Driver produces a
low-frequency sinusoidal ringing signal for analog
telephone loops. This is accomplished by producing
an output pulse stream that is an ampli鏗乪d replica of
the digital input. The output is then 鏗乴tered to produce
a sine wave. The peak-to-peak output level is deter-
mined by the magnitude of the negative high-voltage
dc applied to the device (up to 鈥?70 V).
The required input is a 100 kHz CMOS-compatible
pulse stream, pulse-width modulated (PWM) at the
desired ringing frequency. The output stage consists
of one upper and one lower drive transistor with an
internal control circuit.
The L7590C IC is optimized for low power dissipation
and is available in a 16-pin, surface-mount package.
Applies a battery-backed, single-ended, sinusoidal
ringing signal to the telephone loop
Ringing capability:
鈥?40 Vrms into 5 North American REN
鈥?30 mApeak into 4 German REN
Built-in current limiting
Low power dissipation in idle and ringing modes
Requires 5 V, a high-value negative dc supply, and
a digital input sequence
