TSC2046EQPWRQ1

Texas Instruments · Touch Screen Controllers · TSSOP-16

TSC2046EQPWRQ1 from Texas Instruments, in a TSSOP-16. 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, 2.2 V to 5.25 V operation per the features list (2.7 V to 5.25 V for the internal reference), with +VCC ≥ IOVDD.
2 X+ bidirectional X+ position input to the touch screen, with a driver switch on-resistance of 5 Ω typical and 50 mA maximum drive current.
3 Y+ bidirectional Y+ position input to the touch screen, with a driver switch on-resistance of 5 Ω typical and 50 mA maximum drive current.
4 X- bidirectional X- position input to the touch screen, with a driver switch on-resistance of 6 Ω typical and 50 mA maximum drive current.
5 Y- bidirectional Y- position input to the touch screen, with a driver switch on-resistance of 6 Ω typical and 50 mA maximum drive current.
6 GND power_in Ground; must be connected to a clean ground point.
7 VBAT power_in Battery monitor input, measuring battery voltage from 0 V to 6 V.
8 AUX input Auxiliary input to the ADC.
9 VREF power_in Voltage reference input/output; the internal 2.5 V reference can be overdriven by an external source between 2 V and +VCC.
10 IOVDD power_in Digital I/O power supply, 1.5 V to 5.25 V, which must not exceed +VCC.
11 PENIRQ output Pen interrupt output.
12 DOUT tri_state Serial data output, shifted on the falling edge of DCLK, and high impedance when CS is high.
13 BUSY tri_state Busy output, high impedance when CS is high.
14 DIN input Serial data input; if CS is low, data are latched on the rising edge of DCLK.
15 CS input Chip select input that controls conversion timing and enables the serial input/output register; CS high = power-down mode (ADC only).
16 DCLK input External clock input that runs the SAR conversion process and synchronizes serial data I/O.
