DescriptionThe TFDS4500-TR3 is designed as one kind of low-power infrared transceiver that can be used in (1)notebook computers, desktop PCs, palmtop computers (Win CE, Palm PC), PDAs; (2)digital still and video cameras; (3)printers, fax machines, photocopiers, screen projectors; (4)telecommunication products (cellular phones, pagers); (5)internet TV boxes, video conferencing systems; (6)external infrared adapters (dongles); (7)medical and industrial data collection devices applications. This device is capable of directly interfacing with a wide variety of I/O chips which perform the pulse-width modulation / demodulation function.
Features of the TFDS4500-TR3 are:(1)babyface (universal) package capable of surface mount solderability to side- and top-view orientation; (2)directly interfaces with various super I/O and controller devices and TEMIC's TOIM3000 and TOIM3232 I/Os; (3)few external components required; (4)backward compatible to all TEMIC SIR infrared transceivers; (5)builtin EMI protection no external shielding necessary; (6)compliant to IrDA 1.2 (up to 115.2 kbit/s); (7)wide operating voltage range (2.7 to 5.5 V ); (8)low power consumption (1.3 mA supply current); (9)power sleep mode through Vcc1/SD pin (5 nA sleep current) long range (up to 3.0 m at 115.2 kbit/s).
The absolute maximum ratings of the TFDS4500-TR3 can be summarized as:(1)Supply Voltage Range: -0.5 V to 6 V;(2)Voltage Range of IRED Drive Output: -0.5 V to 6 V;(3)Input Currents: 10 mA;(4)Output Sink Current: 25 mA;(5)Power Dissipation: 200 mW;(6)Junction Temperature: 125 ;(7)Ambient Temperature Range (Operating): -25 to 85 ;(8)Storage Temperature Range: -25 to 85 ;(9)Soldering Temperature: 215 to 240 ;(10)Average IRED Current: 100 mA;(11)Repetitive Pulsed IRED Current: 500 mA;(12)IRED Anode Voltage at Current Output: 6 V;(13)Transmitter Data Input Voltage: -0.5 to Vcc+0.5 V;(14)Receiver Data Output Voltage: -0.5 to Vcc+0.5 V.
