2 General Description
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 short-circuits
outputs for each air-core meter and a real time
angle tracking avoids display errors.
The chip can also drive one small angle air-core
meters (90°).
The communication with the µP is done via a
three wires serial link.
The chip outputs an error status on a special pin.
