General Description
The FMS7401/7401L is a family of Digital Power Control-
lers designed for applications requiring ease of digital based
control over analog based implementations. The FMS7401/
7401L family is an ideal solution to implement ballast
control, motor control and battery management functions.
This family integrates a wide variety of analog blocks with
an 8-bit microcontroller core to offer a complementary
feature set with high performance, low power and small
size in a single chip.
The FMS7401/7401L family is fabricated using CMOS
technology and is fully static. This offers significant power
savings. This family is available in both 8-pin and 14-pin
PDIP packages. SOIC and TSSOP packages are available
upon request.
The FMS7401L is intended for applications using a supply
voltage in the 2.7V to 3.6V range, while the FMS7401 is
suited for applications that use a supply voltage in the 10V to
13.5V range.
