ISL78419規(guī)格書詳情
The ISL78419 is an integrated power management IC (PMIC) for
TFT-LCDs used in central display, rear seat entertainment and
virtual dashboards. The device integrates a boost converter for
generating AVDD, an LDO regulator for VLOGIC. VON and VOFF are
generated by a charge pump driven by the switch node of the
boost converter. The ISL78419 also includes a VON slice circuit,
reset function, and a high performance VCOM amplifier with a
Digitally Controlled Potentiometer (DCP) that is used as a VCOM
calibrator.
The AVDD boost converter features a 1.5A/0.18Ω boost FET with
600kHz/1200kHz switching frequency.
The integrated logic LDO includes a 350mA FET for driving the low
voltage needed by external digital circuitry.
The gate pulse modulator can control the gate voltage up to 30V,
and both the rate and slew delay times are selectable.
The supply monitor generates a reset signal when the system is
powered down based on a user selected threshold level
(programming resistor).
The ISL78419 provides a digitally controlled VCOM output using
I
2C interface. One VCOM amplifier is also integrated in the chip to
provide a fast slewing 150mA drive (sourcing or sinking). The
output of the VCOM is powered up with the voltage stored at the
last programmed 8-bit (internal) EEPROM setting.
The ISL78419 is rated to operate over the temperature range
of (-40°C to +105°C) and is qualified according to AEC-Q100.
