TSC2046EIPWR

Texas Instruments · Touch Screen Controllers · TSSOP-16-EP

TSC2046EIPWR from Texas Instruments, in a TSSOP-16-EP. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 +VCC power_in Power supply; specified performance is 2.7 V to 3.6 V and the operating range is 2.2 V to 5.25 V.
2 X+ passive X+ touch-screen position input; the datasheet gives switch on-resistance of 5 Ω for the Y+ and X+ drivers and an absolute analog input range of −0.2 V to +VCC + 0.2 V.
3 Y+ passive Y+ touch-screen position input; the datasheet gives switch on-resistance of 5 Ω for the Y+ and X+ drivers and an absolute analog input range of −0.2 V to +VCC + 0.2 V.
4 X− passive X− touch-screen position input; the datasheet gives switch on-resistance of 6 Ω for the Y− and X− drivers and an absolute analog input range of −0.2 V to +0.2 V on the negative input.
5 Y− passive Y− touch-screen position input; the datasheet gives switch on-resistance of 6 Ω for the Y− and X− drivers and an absolute analog input range of −0.2 V to +0.2 V on the negative input.
6 GND power_in Ground; the datasheet requires a clean ground point, normally the analog ground, kept away from microcontroller or DSP ground returns.
7 VBAT power_in Battery monitor input; the input voltage range is 0.5 V to 6.0 V.
8 AUX input Auxiliary input to the ADC; the absolute input range is −0.2 V to +VCC + 0.2 V.
9 VREF power_in Voltage reference input/output; the internal 2.5 V reference can be overdriven by an external low-impedance source between 1 V and +VCC.
10 IOVDD power_in Digital I/O power supply; the operating range is 1.5 V to +VCC, and IOVDD must not exceed +VCC.
11 PENIRQ output Pen interrupt output for touch detection.
12 DOUT tri_state Serial data output; data shift on the falling edge of DCLK, and the output is high impedance when CS is high.
13 BUSY tri_state Busy output; the output is high impedance when CS is high.
14 DIN input Serial data input; when CS is low, data are latched on the rising edge of DCLK.
15 CS input Chip select input; it controls conversion timing and enables the serial input/output register, and CS high puts the ADC in power-down mode.
16 DCLK input External clock input; it runs the SAR conversion process and synchronizes serial data I/O.
17 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).

CAD (KiCad official)

  • Symbol: TSC2046EIPWR
  • Footprint: Package_SO:TSSOP-16-1EP_4.4x5mm_P0.65mm
  • 3D model: TSSOP-16-EP (KiCad packages3D, STEP)
  • 3D model files: tsc2046eipwr-etched.step / tsc2046eipwr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); tsc2046eipwr.step / tsc2046eipwr.glb are the bare package body.
