BM81810MUF-M
Automotive Panel Power Management IC
BM81810MUF-M is a power management IC for TFT-LCD panels which are used in car navigation, in-vehicle center panel, and instrument cluster. 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.
