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.

NOTES:
2. These parameters are controlled via design or process parameters and are not directly tested. These parameters are characterized upon initial
design release and upon design changes which would affect these characteristics.
3. Differential Ringing Gain is measured with VRS = 0.795V
RMS
for -100V devices, VRS = 0.663 V
RMS
for -85V devices and VRS = 0.575V
RMS
for -75V devices.
4. Longitudinal Balance is tested per IEEE455-1985, with 368
per Tip and Ring terminal.
5. These parameters are tested 100% at room temperature. These parameters are guaranteed not tested across temperature via statistical
characterization and design.
6. The power dissipation is based on actual device measurements and will be less than worst case calculations based on data sheet supply current
limits.
