POWER-ON SEQUENCE TIMING
POWER-ON SEQUENCE 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
TSC supply (+VDD) ramps up greater than 0.9V. If the TSC
uses the same supply as the the I2C bus pull-up resistors
(VI2C), then a 1F capacitor placed very close to the TSC
supply pin will cause the TSC supply to ramp up more slowly
(refer to the Power-On Sequence timing diagram). If the TSC
supply (+VDD) is different than the supply to the I2C bus pull-
up resistors (VI2C), then VI2C should be turned on before the
TSC supply (+VDD) is powered up.
