BM81810MUF-M - Automotive Panel Power Management

General Description

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).

Key Features

  • AEC-Q100 Qualified(Note 1).
  • Alternative Synchronous Buck DC/DC converter or LDO for VDD output.
  • 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).
  • Swit.
