Power Supply IC Series for TFT-LCD Panels
Automotive Panel Power Management IC
BM81810MUV-M
●General Description
●Features
BM81810MUV-M is
a
power management IC for
AEC-Q100 Qualified(Note 1)
TFT-LCD panels which are used in car navigation,
in-vehicle center panel, and instrument cluster.
Alternative Synchronous Buck DC/DC converter or LDO
for VDD output
This IC incorporates VCOM amplifier, Gate Pulse
Modulation (GPM) in addition to the power supply for
panel driver (SOURCE, GATE, and LOGIC power
supplies). Moreover, this IC has a built-in EEPROM for
sequence and output voltage setting retention.
Synchronous Boost DC/DC converter for AVDD output
with integrated load switch.
VCOM amplifier with 7bit calibrator
Positive charge pump (Integrated diode, x2/x3) for VGH
output
Negative charge pump for VGL output
VGH and VCOM temperature compensation
Gate Pulse Modulation(GPM)
I2C Interface Output Voltage Setting Control Function
(Integrated EEPROM)
Switching frequency switching function
(525KHz, 1.05MHz, 2.1MHz)
