HA16603P/fp contactless switch ade-204-063 (z) rev. 0 dec. 2000 description the HA16603P is an ic for use with metal proximity switches. it can be used for the coin sensor circuit in vending machines and similar microprocessor sensors. features two proximity switch channels the input and output pins are arranged in pairs for convenient printed circuit board mounting. wide operating power-supply voltage range: 4.75 to 30 v low power with a dissipation current of only 2.5 ma normal and inverted outputs can be acquired at the same time. the outputs is available for current-source drive only since the internal circuits are npn transistors with open emitter outputs. ordering information type no. package HA16603P dp-16 ha16603fp fp-16da

HA16603P/fp 7 notes (1) an air-core coil must be used as the sensor coil. (2) this ic has 3 ground pins. all three ground pins must be connected to ground, even if only one channel is used. (3) if the sensitivity is set too high for a sensor coil with bad temperature characteristics, the operating temperature range may become narrow. the operating temperature range for the whole system, including the sensor coil, can be expanded by holding down the sensitivity. sample recommended operating circuit 86 m h l 2 c o2 2,200 p r h2 r d2 r d1 r h1 c o1 2,200 p 86 m h l 2 r l 47 k r l 47 k c i1 c i2 1,000 pf 1,000 pf + 22 m f r l 47 k r l 47 k v cc (24 v) (ch 1 ) (ch 2 ) 12345678 9 10 11 12 13 14 15 16 sensor 1 gnd hys1 s1 s2 hys2 gnd sensor 2 q 2 q 2 v cc c 2 gnd c 1 q 1 q 1 HA16603P/fp (top view)
HA16603P/fp 8 the oscillator frequency is determined by the following formula. f osc = 1 2 p lc o the tank circuit formed by l and c 0 has characteristic impedance shown in the figure. the condition for oscillation for the HA16603P is rd 1/g, and the condition for oscillation to stop is rd > 1/g. 1/g = 2 p f?q. ( w ) z f 1/g when rd is connected to the hysteresis pin, (rd + r cs // rh) 1/g is the condition for oscillation to start, and (rd + rh) > 1/g is the condition for oscillation to stop. note that r cs is the internal resistance of the hysteresis pin. the relationship between oscillation occurring or not and the detection of a metallic object is as follows: oscillation occurs: when no metallic object is detected (i.e. the sensor coil and the metallic object are separated) oscillation stops: when a metallic object is detected (i.e. the metallic object is near the sensor coil) setting the detection distance since the detection distance depends on the q of the sensor coil and the shape, surface area, thickness, and material of the metallic object, it can only be set by testing the completed system. note that rd sets the detection distance.
