MLX10420AA 3-channel air-core gauge driver

The MLX10420 is a µP peripheral for air-core meters control using SIN/COS PWM commands. The circuit controls two independent sets of CMOS power bridges. A ten bit angle is displayed with 9 bits per quadrant. The PWM frequency is set by an on chip oscillator. A power-on self test detects open or shor.
