TSC2000IPW

The TSC2000IPW is designed as a complete PDA analog interface circuit. It contains a complete 12-bit, analog to digital (AD) resistive touch screen converter including drivers, the control to measure touch pressure, and an 8-bit digital-to-analog converter output for LCD contrast control. Its typical applications include personal digita assistants, cellular phones and MP3 players.

TSC2000IPW has twelve features. (1)4-wire touch screen interface. (2)Ratiometric conversion. (3)Single 2.7V to 3.6V supply. (4)Serial interface. (5)Internal detection of screen touch. (6)Programmable 8-, 10- or 12-bit resolution. (7)Programmable sampling rates. (8)Direct battery measurement (0.5V to 6V). (9)On-chip temperature measurement. (10)Touch-pressure measurement. (11)Full power-down control. (12)TSSOP-20 package. Those are all the main features.

Some TSC2000IPW absolute maximum ratings have been concluded into several points as follow. (1)Its Vdd to GND would be from -0.3V to 6V. (2)Its digital input voltage to GND would be from -0.3V to Vdd+0.3V. (3)Its operating temperature range would be from -40°C to 105°C. (4)Its storage temperature range would be from -65°C to 150°C. (5)Its junction temperature would be 150°C. (6)Its TSSOP package thermal impedance would be 93°C/W. (7)Its lead temperature soldering would be 215°C for vapor phase 60s and would be 220°C for infrared 15s. It should be noted that stresses above those listed in absolute maximum ratings may cause permanent damage to device.

Also some TSC2000IPW electrical characteristics are concluded as follow. (1)Its input voltage range would be min 0V and max Vref. (2)Its input capacitance would be typ 25pF. (3)Its input leakage current would be typ +/-1uA. (4)Its battery monitor input voltage range would be from 0.5V to 6.0V. (5)Its battery monitor input capacitance would be 25pF. And so on. At present we have not got so much information about this IC and we would try hard to get more information about it.
