TCA 305 TCA 355 Proximity Switch TCA 305 TCA 355 Bipolar IC Features Lower open-loop current consumption IS < 1 mA Lower output saturation voltage The temperature dependence of the switching distance is lower and compensation of the resonant circuit TC (temperature coefficient) is easier The sensitivity is higher, so that larger switching PG-DSO-8-1 distances are possible and coils of a lower quality can be used The switching hysteresis remains constant as regards temperature, supply voltage and switching distance The TCA 305 even functions without external integrating capacitor. With an external capacitor (or with RC combination) good noise immunity can be achieved The outputs are temporarily short-circuit proof (approx. PG-DIP-14-1 10 s to 1 min depending on package) The outputs are disabled when VS < approx. 4.5 V and are enabled when the oscillator stabilizes (from VS min = 5 V) Higher switching frequencies can be obtained Pb-free lead plating RoHS compliant PG-DSO-14-1 Type Ordering Code Package TCA 305 A Q67000-A2291 PG-DIP-14-1 TCA 305 G Q67000-A2305 PG-DSO-14-1 (SMD) TCA 355 G Q67000-A2444 PG-DSO-8-1 (SMD) Not for new design 02.05 Semiconductor Group 1 TCA 305 TCA 355 TCA 305 A TCA 355 G TCA 305 G Pin Configurations (top view) The devices TCA 305 and TCA 355 contain all the functions necessary to design inductive proximity switches. By approaching a standard metal plate to the coil, the resonant circuit is damped and the outputs are switched. Operation Schematic: see TCA 205 The types TCA 305 and TCA 355 have been developed from the type TCA 205 and are out- standing for the following characteristics: Logic Functions Oscillator Outputs Q not damped H L damped L H Semiconductor Group 2
