Functional Diagram
Description
The 10407 is a MCU peripheral for logometers control using SIN/COS PWM commands. The circuit controls two
independent sets of CMOS power bridges. A ten-bit angle is displayed with a 9 bit per quadrant resolution PWM whose
frequency is set by a crystal oscillator. A power-on self test detects open or short-circuit outputs for each logometer and
a real time angle tracking avoids display errors.
The 10407 can also drive three small angle logometers (90°). A three wire serial link allows bidirectional communication
with the MCU.
