The Future of Analog IC Technology
DESCRIPTION
The MP5414 is a h ighly-efficient fully-integrated
PMU with a current-mode step-u p converter,
four single -pole/double-throw switches, low
drop-out, and a battery charger designed for
battery-powered supply applications.
The step-up converter can start- up from an
input voltage as low as 1.8V. It uses a current-
limited variable-freque ncy control algorithm to
optimize efficiency a nd minimize external
component size and cost. The internal low-
resistance N-Channel MOSF ET switch ca n
withstand up to 10V, a llowing the MP5414 to
produce a high output voltage with high
efficiency from a dual-cell NiCd/NiMH or single-
cell Li-ion battery. In addition, the step-up
converter can disconn ect all load s from the
input DC power supply.
The charger features constant-current and
constant-voltage charging modes with a
programmable charg e current (50mA to
300mA), trickle-charge capability, and a charge-
status indicator. Charging is enabled with an
input voltage greater th an 3.5V, an d is d isabled
when unplugged from the AC ad aptor. The
charger do es not nee d an external reverse-
blocking diode.
The low-dropout linear regulator op erates with
low noise from a 2.7V-to-6.5V input voltage,
and regulat es the out put voltage with 2%
accuracy from 1.25V to 5V.
The MP541 4 is available in a 4mm x 5mm 28-
pin QFN package.
