Detailed Description
The MAX9650/MAX9651 operational rail-to-rail
input/output amplifiers hold the VCOM voltage stable
while providing the ability to source and sink a high cur-
rent quickly (1.3A) into a capacitive load such as the
backplane of a TFT-LCD panel.
Thermal Shutdown
with Temperature Hysteresis
The MAX9650/MAX9651 are capable of high output
currents and feature thermal-shutdown protection with
temperature hysteresis. When the die temperature
reaches +170°C, the device shuts down. When the die
cools down by 15°C, the device turns on again. In a
TFT-LCD application, the duty cycle is very low. Even
with high values of voltage and current, the power dissi-
pation is low and the chip does not shut down.
