INTRODUCTION
The MTE1122 is an Energy Management Controller IC
for single-phase induction motors. This CMOS device
is based on Microchip Technology Inc’s RISC proces-
sor core and proprietary algorithms. When combined
with some external analog components, it will provide
an electronic system that economically reduces the
operating costs of small induction motors by as much
as 58%. It will also allow motors to run cooler and with
less vibration. The system operates on single phase
110 or 220 VAC.
