DESCRIPTION

1 = OUT, 2 = GND, 3 = V_S

The TSOP48.., TSOP44.. series are miniaturized receivers

for infrared remote control systems. A PIN diode and a

preamplifier are assembled on a lead frame, the epoxy

package acts as an IR filter.

The demodulated output signal can be directly decoded by

a microprocessor. The TSOP48.. is compatible with all

common IR remote control data formats. The TSOP44.. is

optimized to suppress almost all spurious pulses from

energy saving fluorescent lamps but will also suppress

some data signals.

This component has not been qualified according to

automotive specifications.

The external components R and C are optional

to improve the robustnes against electrical overstress

(typical values are R = 100 Ω, C = 0.1 µF).

Control circuit

GND

The output voltage V_Oshould not be pulled down to a level

below 1 V by the external circuit.

The capacitive load at the output should be less than 2 nF.
