Figure 1. Timing Diagram
During TSC2003 power-up, the I2C bus should be idle. In other words, the SDA and SCL lines must be high
before the TSC2003 supply (VDD) ramps up greater than 0.9 V. If the TSC2003 uses the same supply as the I
2C
bus pullup resistors (VI2C), then a 1-F capacitor placed very close to the TSC2003 supply pin causes the
TSC2003 supply to ramp up more slowly (see Figure 2). If the TSC2003 supply (VDD) is different than the supply
to the I2C bus pullup resistors (VI2C), then VI2C should be turned on before the TSC2003 supply (VDD) is powered
up.
