ROHM Semiconductor BM81810MUV-M Automotive Panel Power Management IC

ROHM Semiconductor BM81810MUV-M Automotive Panel Power Management IC (PMIC) is optimized for display panels used in-car navigation, in-vehicle center panels, and instrument clusters. The BM81810MUV-M incorporates a VCOM amplifier and Gate Pulse Modulation (GPM), in addition to the power supply for the panel driver (SOURCE, GATE, and LOGIC power supplies). This device also integrates EEPROM for sequence and output voltage setting retention. The BM81810MUV-M includes under-voltage lockout, thermal shut down, over-current protection, over-voltage protection, and under-voltage protection circuits.

The ROHM Semiconductor BM81810MUV-M PMIC is available in a VQFN32SV5050 package and is AEC-Q100 qualified for use in automotive applications.
