RTQ6752-QT
TFT LCD Integrated Power Module for Automotive
General Description
Features
2.5V to 5.5V Input Supply Voltage
The RTQ6752-QT is an I2C interface programmable
power management IC. The IC includes two
synchronous boost converters for PAVDD, one
synchronous NAVDD buck-boost, with 8-bit Calibrator
and one RESET voltage detector. With available in a
WET-WQFN-20L 5x5 package, this device is suitable
for automotive TFT-LCD panel.
I2C Interface
Power-on and Power-off Sequence Free
PAVDD Programmable Output Voltage 5V to 7.3V
PAVDD Output Current Capability up to 200mA
NAVDD Programmable Output Voltage −5V to
−7.3V
NAVDD Output Current Capability up to 200mA
Outputs Power-off Discharge Function
Programmable Voltage Detector
The IC can operate from 2.5V to 5.5V input voltages.
High switching frequency operation prevent that the
switching noise to interfere AM band. Current-limit
functions are provided for all internal- switch converters,
and output-fault shutdown protects all converters
against output-fault conditions, and output the FAULT
signal to communicate with automotive computer.
Programmable soft-start functions for all output voltage
to limit input inrush current during startup.
