Description

Programmable constant current feed

-22 V to -72 V battery operation

The Zarlink MT91600 provides an interface between

a switching system and a subscriber loop, mainly for

short loop SLIC applications. The functions provided

by the MT91600 include battery feed, programmable

constant current, 2 W to 4 W conversion, off-hook

and dial pulse detection, user definable line and

network balance impedance’s and the capability of

programming the audio gain externally. The device is

fabricated as a CMOS circuit in a 28 pin SSOP

package.
