TDE0160
Proximi ty Detector s
Features
■Supp ly Voltage +4 to +36V
■Supp ly Current < 1.2mA
■Loss Resistance 5 to 50kΩ
■Os cillator Frequen cy < 1MH z
■Output Transistors I = 20mA, VCE(sat) ≤ 1. 1V
Description
The TDE0160 is designed to detect metal b odies
by the effect of Eddy currents on the HF loss es of
a coil. It has two complementary open collector
outputs with peak limiting. Hysteresis is
adjustable, and an electronic switching circuit is
incorporated for disabling both outputs.
An internal zener diode maintains the supply
voltage to the circuit in “dipole“ operation.

3 Operating Mode
If IC exceeds ICO = V(ref) / Rd the switch cuts off the output transistor and tests the value of
current IC, with time costant 0.5Cd On power up the internal start system cuts off the output
transistors until VCC reache s a value permitting normal operation of the circuit.
