M5481B7集成电路（IC）的显示驱动器规格书PDF中文资料

M5481B7属于集成电路（IC）的显示驱动器。由意法半导体集团制造生产的M5481B7显示驱动器显示驱动器是一种集成电路 (IC)，可在微处理器 (MPU)、微控制器 (MCU) 或其他电路系统之间提供转换、接口和控制，用于 LCD、LED、OLED、DLP、真空荧光和 AMOLED 等显示器。可能的通信接口和协议包括模拟、BCD、I2C、并行、串行、SMBus、SPI 和 QSPI。

DESCRIPTION

The M5481 is a monolithic MOS integrated circuit produced with a N-channel silicon gate technology. It uses the M5450 die packaged in a 20-pin plastic package copper frame, making it ideal for a 1-digit display. A single pin controls the LED display brightness by setting a reference current through a variable resistor connected either to VDD or to a separate supply of 13.2V maximum. The M5481 is a pin-to-pin replacement of the NS MM 5481.
