General Description
The FMS7401L is a Digital Power Controller designed for
applications requiring ease of digital based control over ana-
log based implementations. The FMS7401L is an ideal solu-
tion to implement ballast control, motor control and battery
management functions. It integrates a wide variety of analog
blocks with an 8-bit microcontroller core to offer a comple-
mentary feature set with high performance, low power and
small size in a single chip.
The FMS7401L is intended for applications using a supply
voltage in the 2.7V to 3.6V range. It is fabricated using
CMOS technology and is fully static offering a significant
power savings. The FMS7401L is available in both 8-pin and
14-pin PDIP, SOIC and TSSOP packages.
