ZMDI, a Global Semiconductor Company, Announces the Release of the ZSPM4551, a Smart Charger for Lithium-Ion Batteries
DRESDEN, Germany, Dec. 10, 2012 /PRNewswire/ – ZMD AG (ZMDI), a Dresden-based semiconductor company that specializes in enabling
energy-efficient solutions, today announces the release of the
ZSPM4551, a DC/DC synchronous switching lithium-ion (Li-ion) battery
charger. As a global supplier of analog and mixed-signal solutions for
automotive, industrial, medical, information technology and consumer
applications, ZMDI focuses on developing families of compact and
high-efficiency products including the ZSPM4551.
The ZSPM4551 is configurable for termination voltage, charge current and
additional variables to allow optimum charging conditions for a wide
range of Li-ion batteries. Its 1MHz switching frequency enables the use
of small filter components, resulting in smaller board space and
reduced system costs.
The ZSPM4551 has an integrated I(2)C(TM) (trademark of NXP) interface, which enables the user to set
application-specific temperature-compensated termination voltages and
control charging currents. It can regulate up to 1.5A continuous drive
The ZSPM4551 features integrated power switches, internal compensation
and fault protection. It offers Li-ion-specific protection for
over-current, over-temperature, battery (VBAT) over-voltage and
charging timeout. It includes supervisory reporting through the NFLT
(inverted fault) open-drain output for interfacing with other
components in the system.
The ZSPM4551 is in a league of its own when it comes to its high level
of integration, up to 92% efficiency with typical loads and ultra-low
power consumption. When the regulator is disabled, the device typically
draws 10µA quiescent current.
“ZMDI is committed to developing advanced high-efficiency solutions to meet
our customers’ variety of needs. Our smart charger, the ZSPM4551,
supports our customers’ direction into portable applications, and this
product is another example of ZMDI’s commitment to providing the very
best solutions for our energy-conscious customers,” stated Edward Lam,
Vice President of Product Marketing and Business Development at ZMDI.
