L7590C Telephone Ringing Driver
Data Sheet
June 1998
Pin Information
Pin Symbol Type
Name/Function
14
VDD
— +5 V Power Supply.
3
GNDD — Digital Ground.
12
GNDR — Ringing Ground.
8
VNEG
— Negative Power Supply. Determines the swing of the ringing generator. Connect
a 1 µF capacitor from VNEG to VREF.
5
VREF
— Internal Reference Voltage. Connect a 1 µF capacitor from VREF to VNEG.
16
CLK
I Clock. Modulated pulse stream. Low = 0 V. High = VDD.
7
OUT
O Ringing Generator Output. Connect to ringing relay contact through a filter.
1
CB1
— Bootstrap Capacitor. Connect a 0.1 µF capacitor between CB1 and CB2.
2
CB2
— Bootstrap Capacitor. Connect a 0.1 µF capacitor between CB1 and CB2.
9
L1
— Filter Inductor. Connect an inductor to pin L2.
10
L2
— Filter Inductor. Connect an inductor to pin L1.
15
EN
— Not Enable. A logic low activates the internal circuitry. A logic high puts the device
in a low-power powerdown mode.
Absolute Maximum Ratings (TA = 25 °C)
Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. These are abso-
lute stress ratings only. Functional operation of the device is not implied at these or any other conditions in excess
of those given in the operational sections of this data sheet. Exposure to absolute maximum ratings for extended
periods may adversely affect device reliability.
