TCA 505 BG IC for Inductive Proximity Switches TCA 505 BG with Short-Circuit Protection Pb-free lead plating RoHS compliant Bipolar IC Features Wide supply voltage of 3.1 to 4.5 V and 4 to 40 V Low current consumption of less than 0.8 mA Integrated output stage for up to 60 mA output current Short-circuit and overload protection of output stages and external components PG-DSO-16-1 Temperature response of the IC compensates that of the coil High noise immunity High switching frequencies up to 5 kHz Useful extra functions Suitable for two-wire AC proximity switches Temperature range 40 to 110 C Type Ordering Code Package TCA 505 BG Q67000-A8341 PG-DSO-16-1 (SMD) TCA 505 B Q67000-A8342 Chip Besides its basic functions (oscillator, demodulator and threshold switch), the bipolar monolithic IC TCA 505 B includes a number of useful extra functions that enable high-grade, inductive proximity switches to be designed for an attractive price/performance ratio and with space savings. Compared to earlier ICs for inductive proximity switches temperature drift, noise immunity and the switching frequency of the IC have been improved. 02.05 Semiconductor Group 1 TCA 505 BG TCA 505 BG Pin Configurations (top view) Pin Definitions and Functions Pin Symbol Function 1 LC Oscillator 2 RDi Distance 3 N.C.
