TCA 305
TCA 355
Proximity Switch
TCA 305
TCA 355
Bipolar IC
Features
q
Lower open-loop current consumption;
I
S
< 1 mA
q
Lower output saturation voltage
q
The temperature dependence of the switching
distance is lower and compensation of the resonant
circuit
TC
(temperature coefficient) is easier
q
The sensitivity is higher, so that larger switching
PG-DSO-8-1
distances are possible and coils of a lower quality can
be used
q
The switching hysteresis remains constant as regards
temperature, supply voltage and switching distance
q
The TCA 305 even functions without external
integrating capacitor. With an external capacitor (or
with RC combination) good noise immunity can be
achieved
q
The outputs are temporarily short-circuit proof (approx.
10 s to 1 min depending on package)
q
The outputs are disabled when
V
S
< approx. 4.5 V and
PG-DIP-14-1
are enabled when the oscillator stabilizes
(from
V
S min
= 5 V)
q
Higher switching frequencies can be obtained
q
Pb-free lead plating; RoHS compliant
