• Description: VoIP Ringing SLIC Family
• Manufacturer: Intersil Corporation

Electrical Specifications
NOTES:
Product Family Cross Reference
The following table provides an ordering and functional cross
reference for the existing HC55180 thru HC55184 products
and the new and improved HC55185 product.
Any of the HC55185 products may be used without the
battery switch function by shorting the supply pins VBL and
VBH together. This provides compatibility with HC55180
type applications which do not require the battery switch.
Application Circuit Modifications
The HC55185 basic application circuit is nearly identical to
that of the HC55180 thru HC55184.The HC55185 requires
an additional resistor to program the transient current limit

feature. This programming resistor is connected from pin 16
(TL) to ground. In addition some component values have
been changed to improve overall device performance. The
table below lists the component value changes required for
the HC55185 application circuit.
The value of RS is based on a 600 termination impedance
and RP1 = RP2 = 49.9 . Design equations are provided to
calculate RS for other combinations of termination and
protection resistance.
The CFB capacitor must be non-polarized for proper device
operation in Reverse Active. Ceramic surface mount
capacitors (1206 body style) are available from Panasonic
with a 6.3V voltage rating. These can be used for CFB since
it is internally limited to approximately 3V . The CDC
capacitor may be either polarized or non polarized.
